We need best LiteSpeed cache settings for ideal performance of WordPress site. If you don’t optimize the settings, the plugin can slow down instead of improving speed.

Only an experienced web developer who has good experience with cache plugins can install the right configuration. We made it easy for beginners of WordPress to use the best settings for LiteSpeed cache plugin.

Litespeed Cache is a WordPress caching plugin that is known for its speed and performance. It is a popular choice among WordPress users because it is easy to use and it offers a lot of features.

Some settings become resource intensive and some may break down the site if not configured properly. But I found that using QUIC.cloud with the correct settings of the LiteSpeed Cache plugin can improve the core web vitals and UX of the site.

In our LiteSpeed Cache review, we have mentioned the features, benefits, speed test results of using both the plugin and QUIC.cloud CDN. In this post you are going to learn the litespeed best settings to make your site better.

WordPress LiteSpeed Cache

If you are using WooCommerce, then you should consider using Litespeed Cache.

It has a special setting for WooCommerce that can speed up your website.

When right settings are turned on, you can see the benefits. You do not need any code to figure out the settings.

They are all obvious. Only thing is you should know which one to set on and off.

Also different hosting services don’t have LiteSpeed Server. In that case, you need to use an alternative or QUIC.cloud.

Default Settings

When you install and activate the cache plugin it comes with some predefined settings. You can keep them as it is and test your speed scores on test tools like GTMetrix, PageSpeed Insights, WebPageTest etc.

If you are satisfied with the results, speed and core web vitals, then you can use them without changing any other settings. But some hosting services servers break or not improve the site speed based on these settings. In that case you need to make some changes to these settings.

When setting up LiteSpeed Cache, it’s essential to configure the LiteSpeed Cache WordPress settings for optimal performance. Start by enabling the cache and setting an appropriate TTL (Time to Live) value. Next, configure the LiteSpeed Cache database optimization options to minimize database queries and improve overall efficiency. This includes enabling object caching and setting a reasonable expiration time.

To further enhance your website’s speed, consider integrating a LiteSpeed Cache CDN (Content Delivery Network). This will serve your static content from multiple global locations, reducing latency and improving load times for visitors worldwide.

Another crucial aspect of LiteSpeed Cache setup is managing the WordPress heartbeat API. By default, the heartbeat API can generate numerous requests, causing unnecessary server load. LiteSpeed Cache heartbeat settings allow you to control the frequency of these requests or disable them entirely for specific pages, such as the dashboard or post editor.

LiteSpeed Cache image optimization is another powerful feature that can significantly reduce page load times. By enabling image optimization, LiteSpeed Cache will automatically compress and resize images, ensuring they are served in the most efficient format and size for each visitor’s device. This not only improves performance but also saves bandwidth.

To achieve the best results, regularly monitor your website’s performance using tools like GTmetrix or Google PageSpeed Insights. These tools will provide valuable insights and suggestions for further optimizing your LiteSpeed Cache WordPress settings, ensuring that your website remains fast, responsive, and user-friendly.

LiteSpeed Cache Best Settings

When it comes to caching, LiteSpeed offers multiple options to configure. You can find the LiteSpeed Cache settings page under “Performance -> LiteSpeed Cache” in your WordPress admin area. In this article, we will cover the best LiteSpeed Cache settings for WordPress.

The first setting you need to configure is “EnableCache“. This setting enables the caching functionality on your WordPress website. We recommend that you enable this setting for better performance.

The next setting is “CachePrivacyMode“. This setting determines who can see the cached version of your website. If you set this setting to “Private“, only logged-in users will be able to see the cached version of your website. If you set it to “Public“, anyone will be able to see the cached version of your website. We recommend that you set this setting to “Public” for better performance.

The next setting is “BrowserCacheTTL“. This setting determines how long the browser should cache static resources on your WordPress website. We recommend that you set this setting to a value of “3600” for better performance.

The next setting is ” CrawlerIpAccess“. This setting allows you to specify which IP addresses can access the cached version of your website. We recommend that you set this setting to “*” for better performance.

LiteSpeed Cache setup

Litespeed’s cache plugin is one of the easiest to use and configure. We’ll go over the basics of setting it up for maximum speed and performance.

First, you’ll need to install and activate the plugin. Then, go to Settings > LiteSpeed Cache and click on the General tab.

In the General tab, you’ll want to check the following settings:

Enable cache: This will turn on caching for your website.

Cache TTL: This is how long Litespeed will keep cached files before refreshing them. The TTL can be set in seconds, minutes, hours, or days. We recommend setting it to 1 hour for most websites.

Public Cache: This setting controls whether non-logged in users will see cached versions of your pages or not. If you’re not sure what to choose, we recommend checking this box.

Private Cache: This setting controls whether logged in users will see cached versions of your pages or not. If you’re not sure what to choose, we recommend checking this box.

feed cache: This setting controls whether RSS feed items will be cached or not. If you’re not sure what to choose, we recommend checking this box.

Enable Static Files: This setting allows Litespeed to serve static files (like CSS and JS) from its cache. We recommend checking this box.

Enable Browser Cache: This setting allows visitors’ browsers to cache static files from your website. We recommend checking this box.

General Settings

  1. General
  2. Cache
  3. CDN
  4. Image Optimization
  5. Page Optimization
  6. Database
  7. Crawler
  8. Toolbox

Each of these basic settings will have sub-settings to improve your speed score. Some settings work out for all site users, hosting service and CDN. But for some, you need to test yourself if it works out correctly.

This may sometimes take time in clearing the cache, testing the speed and UX tools and then switching off the settings. Whenever you are in doubt, leave the default settings.

This setting is useful to purge your LiteSpeed Cache at an individual level. There are different types of purge level settings like –

  1. Purge Front Page
  2. Purge pages
  3. … 403 error
  4. Purge 404 error
  5. Purge 500 error

  10. Purge All – Unique CSS
  11. Purge All – LQIP Cache
  12. .. – Gravatar Cache
  13. Purge All
  14. Empty entire cache

Purge means to clear the cache on the server and CDN. The last two settings are useful if your front end is not displaying as intended. Even if you make changes to the site design, it may not display correctly. In such a situation, using the Empty entire cache can be useful. But it should not always be used. As that will reduce the performance speed of the site.

You can also purge the cache by category, post id, tag, url.


  1. Export Settings
  2. Import Settings
  3. Reset All Settings

If you want to use the same LiteSpeed Cache settings on another site, then you can export and import them. The exported settings file is a .data file. Then you can import those settings into a new site. It saves time to configure all the settings again on a fresh site. Sometimes, settings can cause issues and even after purging the cache, the site may not work as intended. In such a case, you can reset all the LiteSpeed Cache settings to their default and start fresh.

View .htaccess

LiteSpeed Cache View .htaccess

The LiteSpeed Cache settings will add some code to your .htaccess file. This is a file stored in the root directory of your site. It is an important configuration file for your site. You can view the file path and contents of .htaccess here.

  1. Frontend .htaccess Path
  2. Backend .htaccess Path

Heartbeat Control

You do want to limit the heartbeat timing, as it consumes a lot of resources. Most cache plugins only provide a single control of Heartbeat. But in the LiteSpeed Cache plugin case several settings are provided.

  • Frontend Heartbeat Control – ON
  • Frontend Heartbeat TTL – 120
  • Backend Heartbeat Control – ON
  • Backend Heartbeat TTL – 0
  • Editor Heartbeat – ON
  • Editor Heartbeat TTL – 60

Most of the heartbeat settings improve the WordPress dashboard performance by performing quick operations.

  • System Information
  • Passwordless Link
  • Notes

The site and server information is mentioned above. But if you want to provide admin access to the LiteSpeed technical support team, you can create a passwordless link and send it to them. In that way they can debug your site for LiteSpeed Cache settings or issues and make changes.

Debug Settings

  • Disable All Features
  • Debug Log
  • Admin IPs
  • Debug Level
  • Log File Size Limit
  • Log Cookies
  • Collapse Query Strings
  • Debug URI Includes

  1. GetSocialGuide says:

    This is a fantastic post that contains a lot of useful information. I appreciate you writing on LiteSpeed Cache for WordPress since it’s really useful to us.

  2. Hello, I have a question about LiteSpeed Cache. Do you need to use these third-party cloud and redis services in this plugin to see positive differences in website speed. And why, after installing this plugin, the database is many times larger. I have a small website on the lite speed server https://www.totemat.pl/ and I do not know why it is that when I run this plugin, the website works slower than faster according to google page speed. Maybe you have any suggestions?

    1. @Thanks for your question. You can use LS Server + LS Cache + Cloudflare (Free) and see the difference. Also the default settings of LS cache are good enough to give good speed. Check if you have Adsense or any other third-party JS code enabled. They can slow down. Check with WebPageTest tool to see the waterfall where the resources are taking time. Then you can reduce that. Also, DB optimization tool is there in LS cache. You can optimize the db with that. Let me know if you have any other questions.

    2. David Garofalo says:

      @TOTEMAT I am just starting using this plugin. I see your site as of today (10-5-2023) runs quick. Did you stay with Lightspeed cache alone? Or did you combine with a CDN? If you are willing to share your experience I’d apricate it. tyia
