100% PageSpeed and GTmetrix Scores for WordPress with LiteSpeed Cache Settings

Website speed optimization is crucial for SEO and user experience. Slow-loading websites lead to higher bounce rates, preventing conversions and traffic growth. With the LiteSpeed Cache plugin, you can significantly boost your site’s performance and achieve perfect scores on PageSpeed and GTmetrix.

This guide will walk you through the steps to configure LiteSpeed Cache settings for optimal performance. We have tested these configurations on multiple websites, and the following configurations are the common settings that yielded the best results.

Let’s get to it!



1. LiteSpeed Overview

LiteSpeed is a high-performance web server designed to accelerate websites. It offers an event-driven architecture that handles more traffic with fewer processes, reducing resource usage and improving page speed. LiteSpeed has two editions:

  • LiteSpeed Enterprise: Suitable for hosting multiple websites or shared hosting environments.
  • OpenLiteSpeed: An open-source version ideal for individual websites.

LiteSpeed Cache is a server-level cache product that optimizes dynamic content on web pages. Available as a plugin for WordPress, it offers advanced caching functionality and optimization features compatible with any web server, including Nginx and Apache.

Frequently Asked Questions About Using Litespeed Cache with WordPress


1. How do I know if LiteSpeed Cache is working properly on my site?

To verify that LiteSpeed Cache is functioning correctly:

Check Headers: Use a tool like Uptrends or your browser’s developer tools to inspect the HTTP headers of your website. Look for the header x-litespeed-cache: hit. This indicates that the page is being served from the cache.

Performance Testing: Use tools like GTmetrix, PageSpeed Insights, or WebPageTest to analyze your site’s performance before and after enabling LiteSpeed Cache. Significant improvements in load times and performance scores are indicators that the cache is working effectively.

Cache Status: Visit the LiteSpeed Cache plugin dashboard in your WordPress admin area to view cache status, including hit and miss ratios, which will give you insight into how well the caching is performing.

2. Should I use QUIC.cloud or Cloudflare for my CDN?

Both QUIC.cloud and Cloudflare are excellent CDNs, but the choice depends on your specific needs:

QUIC.cloud: This CDN is specifically optimized for LiteSpeed Cache and integrates seamlessly with LiteSpeed servers. It offers dynamic content caching and additional optimization features that work in tandem with LiteSpeed Cache.

The standard plan provides full features, including DDoS protection and access to all PoPs, making it ideal for sites looking to maximize performance.

Cloudflare: Cloudflare offers robust free plans and is known for its wide range of security features, including DDoS protection and a large network of PoPs. It’s a versatile option that works well with various web servers.

If using Cloudflare, consider the Super Page Cache for Cloudflare plugin to integrate it with LiteSpeed Cache.

3. What should I do if my site’s performance is still poor after configuring LiteSpeed Cache settings?

If your site is not performing well even after configuring LiteSpeed Cache settings:

Check Configurations: Ensure that all LiteSpeed Cache settings are configured correctly according to the guide.

Additional Plugins: Use additional optimization plugins like Perfmatters to manage bloat, preload critical resources, and disable unnecessary scripts on specific pages.

Hosting Resources: Verify that your hosting plan provides adequate resources (CPU, RAM, etc.). Upgrading to a plan with better resources or a super Fast WordPress & Woocommerce Hosting like Hostious.io might guarantee you resolve the issue.

Third-Party Scripts: Minimize the use of third-party scripts and plugins that may be causing delays. Use tools like Chrome DevTools to identify and address slow-loading resources.

4. Can I use both QUIC.cloud and Cloudflare together on my site?

While it is technically possible to use both QUIC.cloud and Cloudflare together, it adds complexity to your setup:

Choose One for Simplicity: It’s usually best to select one CDN to avoid potential conflicts and simplify configuration. QUIC.cloud integrates seamlessly with LiteSpeed Cache settings, while Cloudflare offers extensive features and is highly reliable.

Configuration: If you decide to use both, ensure that configurations do not overlap or conflict. For instance, use Cloudflare for static content caching and QUIC.cloud for dynamic content caching.

5. How do I optimize images for better performance with LiteSpeed Cache?

Optimizing images is crucial for improving load times and performance:

Enable Image Optimization: In the LiteSpeed Cache settings, navigate to the Image Optimization settings and enable features like Auto Request Cron and Auto Pull Cron.

WebP Conversion: Turn on the Create WebP Versions and Image WebP Replacement settings to serve lighter WebP images instead of larger PNG or JPEG files.

Lazy Loading: Enable Lazy Load Images to defer the loading of images until they are needed, improving initial load times.

LQIP (Low-Quality Image Placeholders): Consider enabling LQIP to display low-quality placeholders while high-quality images are loading, enhancing user experience without sacrificing performance.

Avoid Duplicates: Ensure that you are not using multiple image optimization plugins simultaneously, as this can cause conflicts and processing errors.
