How We Secured & Optimized a WordPress Website for SSL, CPU Usage & Speed (Real Case Study)

Introduction — Real-World WordPress Fixes, Not Just Theory

From Problems to Practical Solutions

If you’ve ever dealt with a slow or CPU-intensive WordPress site, you know how frustrating it gets. One day, everything seems fine. The next day? The site is down, the CPU is maxed out, and you’re getting timeout errors or alerts from your hosting provider. Even worse—some visitors see “Not Secure” warnings because SSL isn’t configured correctly or redirect rules are misbehaving.

We recently worked on a real WordPress project that was facing all of these issues at once—SSL misconfiguration, high CPU usage, caching conflicts, and unoptimized core files. And the best part? We fixed it without depending on heavy plugins or premium tools. Everything was done through clean server-level configuration, with an emphasis on .htaccess, wp-config.php, HSTS headers, and real-time testing using tools like SSL Labs and DNS Checker.

In this blog, we’re going to walk you through the exact steps we followed, why each step was important, and how you can implement the same fixes on your site—whether you’re a developer, freelancer, or business owner managing your own WordPress installation. We’re not going to use our client’s actual domain for privacy and security reasons. So throughout this post, you’ll see us use example1.com or similar placeholders to demonstrate the setup.

Our goal with this blog isn’t just to share a case study—but to provide a simple, step-by-step framework you can follow, no matter your technical level. Even if you’re just in 10th grade and curious about WordPress—this post is written for you too.

So grab a cup of coffee or chai, and let’s fix WordPress the smart way—from the inside out.

🛡️ Fixing SSL: Enforcing HTTPS, Adding HSTS & Avoiding Redirect Loops

When we first audited the website (example1.com), one of the biggest issues we found was with how HTTPS was implemented. While the SSL certificate was active, the website wasn’t enforcing secure connections consistently. It had multiple redirect chains, sometimes from http://example1.com to https://example1.com, then again to https://www.example1.com. This kind of redirect hopping not only slows down the site but also negatively impacts SEO and security.

🚨 Initial Issues Identified

We ran the domain through a series of tools to assess HTTPS behavior and SSL grade:

• SSL Labs: Initially gave the site a B grade due to missing HSTS (HTTP Strict Transport Security) and ambiguous redirection logic.
• Redirect Checker: Showed a multi-step redirection chain, including some 302s and inconsistent canonical redirects.
• httpstatus.io: Detected redundant redirect loops from HTTP to HTTPS and then to the www version.
• Chrome DevTools (Network tab): Inconsistent status codes (307 Temporary Redirect, 301, and 302) on internal links, images, and assets, which confused the browser cache and impacted loading speed.

These results clearly pointed toward poor SSL enforcement and improperly stacked redirects—mostly caused by conflicting .htaccess rules, cPanel-level forced redirects, and remnants of plugin-generated logic.

🧹 Cleaning Up .htaccess for Clean Redirects

To take full control, we decided to handle all HTTPS redirection exclusively from .htaccess—eliminating plugin and hosting-level interference.

Here’s the final snippet we implemented at the top of .htaccess:

# BEGIN Enforce HTTPS and WWW
RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ https://www.example1.com/$1 [L,R=301]
# END Enforce HTTPS and WWW


This rule does three things in one clean step:

1. Forces HTTPS
2. Forces www as the canonical version
3. Executes a single 301 redirect without chaining

We tested this revised logic again through all the above tools, and the results came back clean:

• One-step redirect to https://www.example1.com
• SSL Labs upgraded the grade to A+
• No loops or mixed-content warnings
• Consistent HTTPS loading across devices and browsers

⚙️ Fixing cPanel Redirection Conflicts

One often-overlooked source of conflict is cPanel’s built-in redirection tools. In this case, the hosting environment had HTTPS enforced via:

• cPanel > Domains > Force HTTPS Redirect (ON)
• cPanel > Redirects > Permanent Redirect from example1.com to https://example1.com
• Some AutoSSL-related entries in cron jobs and SSL/TLS Manage Sites

These server-level settings were adding invisible redirects on top of our .htaccess, causing redirect chains and even duplicate headers in some server responses.

To fix it:

• We disabled the Force HTTPS toggle inside cPanel for the domain
• Deleted any active redirects from the “Redirects” section
• Cleaned up AutoSSL jobs and ensured no conflicting rules remained

Once we handed over full redirection control to .htaccess, all problems related to redirect chains disappeared instantly.

🔐 Enabling HSTS for Long-Term Security

To strengthen browser-level trust and prevent downgrade attacks, we added the following line to our .htaccess, just below the HTTPS redirect rules:

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"


This tells browsers to always connect to your site via HTTPS—even if someone tries to access it via HTTP or another insecure method. It also makes your site eligible for the HSTS Preload List in Chrome, Firefox, Edge, and others.

We submitted example1.com to the Chrome HSTS preload submission tool, and received a pending confirmation after verifying all criteria were met.

✅ Results After Fix

Once all adjustments were made, we re-tested everything:

This approach gave us full control of SSL enforcement using only .htaccess, eliminated plugin and server-level conflicts, and ensured a clean, SEO-friendly URL structure.

Next, we’ll tackle the CPU usage issue, including how unnecessary background processes, bots, and bloated cron jobs were silently consuming server resources—and how we fixed that with smart wp-config.php tweaks, plugin audits, and .htaccess rules.

🧾 Final Steps We Took to Fix the SSL & Redirection Issues

To permanently fix the SSL, redirect chain, and HTTPS enforcement issues for example1.com, we followed a precise and structured approach that ensured performance, SEO, and browser trust remained intact.

Here’s a recap of the final steps we implemented:

1. Disabled cPanel’s Force HTTPS & Redirects to prevent server-side conflicts.
2. Cleared all plugin or theme-based redirection rules to avoid duplication and loops.
3. Cleaned and customized .htaccess to handle HTTPS + www redirection in a single 301 step.
4. Tested all redirects across industry tools like SSL Labs, Redirect Checker, and httpstatus.io until results showed a single, clean, secure redirect.
5. Enabled HTTP Strict Transport Security (HSTS) via .htaccess with max-age=31536000; includeSubDomains; preload.
6. Submitted the domain to the Chrome HSTS preload list after verifying all required parameters.

By taking full control of the redirection logic and handling everything through the .htaccess file (instead of scattered settings across cPanel and plugins), we were able to achieve an A+ SSL rating, clean redirects, and bulletproof security—all while improving performance.

Now that SSL was fully optimized, it was time to turn our attention to another silent killer of website performance—high CPU usage.

Let’s break down how we discovered the root causes, and the steps we took to fix them.

⚙️ Optimizing WordPress CPU Usage & Reducing Server Load

One of the most critical problems we encountered on example1.com was unexpectedly high CPU usage on a shared hosting plan, which was causing performance lags, occasional 503 errors, and backend timeouts—especially during peak traffic hours.

This wasn’t just a resource issue. Upon investigating, we found that WordPress itself was not optimized to handle traffic, bots, and background processes efficiently. Let’s walk you through the process of identifying and resolving the culprits.

🔎 Step 1: Auditing CPU Usage Patterns

Using the hosting provider’s cPanel Resource Usage and Awstats, we analyzed which processes were spiking CPU usage. We also used tools like:

• Wordfence Live Traffic: To see real-time requests and bots hitting the site
• Query Monitor plugin: To inspect slow database queries and API calls
• Top Processes via SSH (for VPS/Dedicated setups): When applicable

We observed:

• Frequent hits from bad bots and crawlers
• Constant execution of wp-cron.php
• Some plugins (especially SEO and image optimizers) consuming high memory
• Dozens of 404 requests to /xmlrpc.php and /wp-login.php from unknown IPs

🛠️ Step 2: Tuning wp-config.php and Setting Real Cron Jobs to Reduce Load

To reduce background processing and improve how the server handles requests, we added a few essential constants to the wp-config.php file. These changes helped offload unnecessary operations and gave us more control over memory and scheduled tasks and improved performance under load.

Here’s what we added:

// Disable WP-Cron and replace with a real server-side cron job
define(‘DISABLE_WP_CRON’, true);

// Set safe memory limits to prevent PHP from using excessive resources
define(‘WP_MEMORY_LIMIT’, ‘128M’);
define(‘WP_MAX_MEMORY_LIMIT’, ‘256M’);

// Optional: Disable automatic updates to reduce load during peak traffic
define(‘AUTOMATIC_UPDATER_DISABLED’, true);

Disabling the default WordPress Cron system was a game-changer. Normally, wp-cron.php is triggered on every page load, which can lead to excessive CPU usage—especially on websites with high traffic.

Instead, we scheduled a real cron job through the hosting panel (in this case, cPanel) that runs WordPress scheduled tasks at regular intervals (e.g., every 15 minutes) to handle background tasks more efficiently. Here’s the exact command we used:

*/30 * * * * wget -q -O – https://example1.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1

How We Set This Up in cPanel:

We logged in to the hosting account’s cPanel dashboard, navigated to the “Cron Jobs” section, and added the above command with a 15-minute interval. This setup ensures scheduled tasks like checking for updates, sending emails, and triggering backups run smoothly — without being invoked hundreds of times a day by user visits.

🔧 Tech Note: The >/dev/null 2>&1 at the end of the command suppresses output and error logs to avoid filling up server log space.

If your server doesn’t support wget, you can replace it with curl like this:

*/15 * * * * curl -s https://example1.com/wp-cron.php?doing_wp_cron > /dev/null 2>&1

This small but powerful tweak alone resulted in a noticeable drop in CPU usage. Cron tasks ran more predictably and didn’t interfere with live user activity.

🔐 Step 3: Blocking Bad Bots & XMLRPC Attacks via .htaccess

To cut down the resource waste from bot attacks and brute-force login attempts, we hardened the .htaccess file:

# Block xmlrpc.php
<Files xmlrpc.php>
Order Deny,Allow
Deny from all
</Files>

# Block common bad bots
BrowserMatchNoCase “AhrefsBot” bad_bot
BrowserMatchNoCase “SemrushBot” bad_bot
BrowserMatchNoCase “MJ12bot” bad_bot
Order Allow,Deny
Allow from all
Deny from env=bad_bot

We also blocked repeated access to /wp-login.php from unknown or foreign IPs using a combination of security plugins and .htaccess logic.

🔌 Step 4: Auditing and Replacing Heavy Plugins

Some plugins were CPU hogs. We replaced:

• Heavy image optimization plugins with lighter ones like ShortPixel
• Complex security plugins with Wordfence (with real-time traffic logging disabled)
• Replaced legacy SEO plugin with lightweight alternatives like Slim SEO (optional)

We also removed plugins that were not in use but still loaded in the background.

🧪 Step 5: Testing Results After Optimization

After all tweaks, we ran the following tests and monitored performance for 7 days:

🧾 Final Fixes for CPU Usage

Here’s a summary of everything we implemented to fix CPU usage issues:

1. Audited top processes and plugin performance
2. Disabled WP Cron via wp-config.php and moved to server-based scheduling
3. Set memory limits for better PHP performance handling
4. Hardened .htaccess to block bots, XML-RPC, and login abuse
5. Optimized or replaced heavy plugins
6. Monitored and confirmed improvements using hosting resource stats and external tests

This gave the site breathing room, improved its stability, and laid the foundation for faster load times—even during traffic spikes.

🧹 Cleaning & Optimizing .htaccess for Performance, SEO & Crawl Efficiency

The .htaccess file is one of the most powerful configuration files in a WordPress website. It’s often misused or left cluttered with conflicting directives—especially when multiple plugins or cPanel redirection settings have injected rules over time.

For our case with example1.com, this file had become bloated and messy. There were redundant rules, multiple redirect layers, and even legacy plugin leftovers that were no longer in use. This wasn’t just bad practice—it was actively hurting performance and SEO.

Let’s walk through what we found, how we cleaned it up, and what the final optimized .htaccess looked like.

🧯 Step 1: Reviewing Existing Rules

Before making any changes, we backed up the original .htaccess file. It contained:

• Multiple RewriteCond rules for HTTPS and www redirection—stacked one after another
• Old plugin-generated rules (like caching and redirection plugins that were no longer active)
• Conflicting HSTS rules added by both cPanel and security plugins
• Disabled rules and commented code cluttering readability

This caused:

• Multiple chained redirects (301 → 301 → 200)
• Conflict with SSL setup
• Increased server response time
• Misleading search engine signals (due to duplicate content on www and non-www)

🧼 Step 2: Creating a Clean, Unified Redirect Strategy

Our goal was to handle all redirections (non-www to www and HTTP to HTTPS) in one clean rule block, using a single 301 redirect to ensure fast resolution and proper SEO signals.

Here’s the exact code we added:

RewriteEngine On

# Redirect HTTP to HTTPS and non-www to www
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ https://www.example1.com/$1 [R=301,L]

# Enable HSTS for one year and preload
<IfModule mod_headers.c>
Header always set Strict-Transport-Security “max-age=31536000; includeSubDomains; preload”
</IfModule>

This small yet powerful block:

• Handles everything in one SEO-friendly 301 redirect
• Avoids redirect loops
• Loads faster than plugin-based or cPanel-based redirection
• Complies with the HSTS preload policy

🧪 Step 3: Testing with Tools Before & After Fix

To ensure our new rules were effective and didn’t break anything, we tested using:

• 🔁 https://httpstatus.io: Showed single-step 301 redirect from http://example1.com → https://www.example1.com
• 🔐 https://www.ssllabs.com/ssltest/: Rated A+ after HSTS inclusion
• 🔄 https://redirect-checker.org/: Confirmed no intermediate hops or redirect loops
• 📉 Google Search Console: Cleared all previously reported URL mismatch or duplicate issues
• 🔍 Screaming Frog SEO Spider (Desktop tool): Reduced crawl depth, improved canonical tagging, and fixed non-canonical redirection issues

🛠️ Step 4: Removing cPanel Redirects and Plugin Conflicts

To avoid duplicate or conflicting logic, we also:

• Deleted redirection rules created in cPanel via “Redirects” panel
• Disabled plugin-based redirects (like those set up in Rank Math or Redirection plugin)
• Cleared cache from plugins like LiteSpeed, W3 Total Cache, or WP Super Cache to ensure new rules were active
• Checked for .user.ini or php.ini overrides that may conflict with .htaccess (none were found in our case)

🧾 Final .htaccess Optimization Steps

In the end, our clean and efficient .htaccess strategy included:

1. A single unified rule for HTTPS + www redirection
2. Proper use of 301 redirects for permanent changes (great for SEO)
3. Full HSTS integration for strong browser-level HTTPS enforcement
4. Cleanup of old plugin and cPanel rules to eliminate conflicts
5. Cross-tool testing to ensure compatibility, SEO compliance, and improved crawlability

This helped the website not only load faster but also pass SEO audits, improve crawl rates, and eliminate indexing of duplicate or non-canonical URLs.

🔧 Plugins & Tools Used (and Their Alternatives)

While we manually optimized most of the configurations to ensure total control and precision, we understand that not every website owner or developer will want to do all of this manually. So in this section, we’ll walk you through the plugins and tools we used in our real-world case (example1.com), along with tested alternatives that are still reliable and working as of 2025.

🛠️ Tools We Used for Testing, Auditing, and Debugging

Here are the exact tools we used during the process to identify problems, verify our fixes, and validate everything from redirection logic to security headers:

• SSL Labs – To test SSL implementation, TLS protocols, and get a full security grade. We started with a B due to missing HSTS, but post-optimization we achieved A+.
• Redirect Checker – Used to test URL redirection chains. It showed that our original setup had multiple 301s; we fixed it to a clean one-step 301.
• httpstatus.io – Confirmed the HTTP to HTTPS and non-www to www redirection logic and checked header responses.
• Security Headers by Mozilla – To check if headers like Strict-Transport-Security, Content-Security-Policy, and others were correctly implemented.
• Google Search Console – Notified us about duplicate URLs and insecure links; post-fix, it stopped reporting these issues.
• Screaming Frog SEO Spider – Helped crawl the website before and after the changes, confirming improvement in canonical URL detection and redirect response codes.

🔌 Plugins That Could Help Automate These Fixes (If You’re Not Doing It Manually)

While we implemented everything manually for more control and performance, these plugins can help beginners and non-technical users implement similar optimizations safely:

• Really Simple SSL
  Automatically detects SSL and configures your site to run over HTTPS. Also attempts to configure HSTS if supported by the server.
  ✅ Still working and frequently updated in 2025.
• Redirection
  Helps manage 301 redirects and monitor 404 errors.
  Be cautious: overuse or conflict with .htaccess rules can lead to redirect loops. Use it cleanly.
• WP Htaccess Editor
  A safe way to edit the .htaccess file from the dashboard if you’re not comfortable using FTP or file managers.
• HTTP Headers Plugin
  Allows you to add and manage HTTP response headers like Strict-Transport-Security, X-Content-Type-Options, etc.
• WP Rocket / LiteSpeed Cache / W3 Total Cache
  These plugins can handle browser caching, compression, and cleanup of expired cache entries, which also affects CPU usage. Use just one at a time to avoid conflicts.
• Health Check & Troubleshooting
  Excellent for identifying plugin or theme conflicts that may be increasing CPU load or interfering with server performance.

🤖 Optional Advanced Tools

If you’re a developer or want to go a step further:

• Cloudflare – Can enforce HTTPS, enable HTTP/3, apply security headers at the edge, and reduce CPU load by serving assets directly from their CDN.
• UptimeRobot / Better Uptime – Helps monitor downtime or performance issues caused by misconfigured SSL or redirect errors.
• Sitebulb – Advanced auditing for agencies and developers wanting granular crawl data and performance insights.

✅ Final Plugin/Tool Checklist

Here’s a quick checklist you can save for optimizing any WordPress website without deep technical skills:

• • SSL Labs (for security testing)
  • httpstatus.io (for redirect path analysis)
  • Redirect Checker (to confirm 1-step 301s)
  • SecurityHeaders.com (for header audit)
  • Google Search Console (for indexing issues)
  • Screaming Frog (for crawl validation)
  • Really Simple SSL (if not handling manually)
  • WP Htaccess Editor (for safe editing)
  • HTTP Headers Plugin (for security header injection)
  • One performance plugin (WP Rocket / LiteSpeed / W3 Total Cache)

Next, we’ll cover CPU Usage Optimization via wp-config.php Tweaks, including the real bottlenecks we found and the simple, safe ways to keep your hosting server cool and stable—even during heavy traffic spikes.

⚙️ CPU Usage Optimization via wp-config.php Tweaks

When you’re running multiple WordPress sites—especially with resource-intensive tools like Elementor, LiteSpeed Cache, and solid security plugins—it’s easy to hit CPU limits on shared or low-tier hosting. In our real-world case with example1.com, we noticed CPU spikes were often triggered by scheduled tasks, bots crawling site actions, and unnecessary background processes. Here’s exactly what we did to streamline performance and reduce CPU load, without affecting SEO or user experience.

⏱️ 1. Disabling Default WP-Cron

By default, WordPress triggers wp-cron.php on every page load, which can mean dozens of cron initiations per minute. That’s CPU intensive! We disabled this feature with a simple tweak:

// In wp-config.php
define(‘DISABLE_WP_CRON’, true);

Then, we replaced it with a real, server-driven cron job via cPanel under Advanced → Cron Jobs:

*/15 * * * * php /home/youruser/public_html/wp-cron.php > /dev/null 2>&1

This setup executes WP-Cron every 15 minutes, dramatically cutting down CPU spikes while keeping scheduled tasks like backups or plugin updates running reliably.

🛑 2. Limiting Heartbeat and Autosave

WordPress Heartbeat calls also add up—especially with Elementor editing sessions. To reduce this without affecting functionality, we added:

// Limit heartbeat to every 60 seconds
add_filter(‘heartbeat_send’, function($response, $screen_id) {
if (in_array($screen_id, [‘post’, ‘page’, ‘elementor’])) {
return 60;
}
return $response;
}, 10, 2);

This reduces the frequency of AJAX calls during editing, thus easing load during content creation.

🧹 3. Cron Outside wp-config: Why It Matters

We didn’t stop there. We ensured there were no legacy WP-Cron triggers hiding in functions.php or unused plugins. Cleaning up redundant cron jobs not only safeguards CPU but removes backdoors that might run without your knowledge.

🚫 4. Disabling XML‑RPC & REST Endpoints

To block unnecessary access points that can be exploited or crawled by bots, we added to the .htaccess:

<Files xmlrpc.php>
Require all denied
</Files>

This aligns with our earlier plugin-based block but ensures server-level lockdown to protect CPU and security.

🧼 5. Keeping Plugin Activity Lean

We audited active plugins thoroughly:

• Disabled any redundant cron tasks (like some backup or social-share plugins).
• Checked that LiteSpeed Cache’s scheduled tasks were limited in frequency.
• Removed unused security scans or maintenance routines that ran hourly/daily.

🧾 6. wp-config.PHP CPU Super Check-list

Here’s a refined checklist you can apply across any site to reduce CPU usage efficiently:

define(‘DISABLE_WP_CRON’, true);

// Optional: Limit post revisions to reduce autosave frequency (not CPU heavy but cleanup wise)
define(‘WP_POST_REVISIONS’, 5);

// Reduce Heartbeat frequency
add_filter(‘heartbeat_send’, function($response, $screen_id) {
return in_array($screen_id, [‘post’, ‘page’, ‘elementor’]) ? 60 : $response;
}, 10, 2);

Plus, server cron setup:

*/15 * * * * php /home/you/public_html/wp-cron.php > /dev/null 2>&1

And .htaccess lock-down for xmlrpc.php as shown above.

✅ Final Wrap-up for wp-config.php Optimization

By combining controlled triggering of WP-Cron, throttling the Heartbeat API, and auditing plugins, we turned high CPU usage into a smooth, predictable load pattern. All scheduled tasks and content features still work as expected, and SEO, caching, and user experience remain unhindered.
