LiteSpeed Cache for WordPress (LSCWP) is an all-in-one site acceleration plugin, featuring an exclusive server-level cache and a collection of optimization features.
LSCWP supports WordPress Multisite and is compatible with most popular plugins, including WooCommerce, bbPress, and Yoast SEO.
Because LiteSpeed Cache for WordPress takes advantage of the LSCache technology built directly into the LiteSpeed Web Server our servers use, it reduces overhead and is more efficient than the usual PHP-based caching plugins.
LiteSpeed Cache is included for free with our Performance and Pro Reseller hosting plans, as well as it could be ordered as an Addon to our shared web hosting plans or Boost for the lesser reseller web hosting packages.
Configuring WordPress with LiteSpeed is fairly easy, however you'll first need to make sure you've disabled any existing caching plugins.
To get started with the plugin, you'll first need to:
2) Login to the WP Dashboard and install the LiteSpeed Cache plugin: Plugins >> Add New >> search: LiteSpeed Cache >> Install Now >> Activate:
Once the plugin is activated, go to: LiteSpeed cache >> Cache >> and click on Save Changes >> to enable caching:
LiteSpeed Cache has a ton of great features, which can be split into two main departments: Page caching and Page optimisation.
Page caching works with the existing site code - it caches it and serves it faster on the next visit. In most cases you can use that out of the box, without any changes needed.
Some of the page caching options you'll find in the plugin are:
Server-side page caching - That's the plugin's core functionality - using the server to generate cached pages rather than the slower and more resource intensive PHP.
QUIC.CLOUD – the first and only content delivery network with the ability to cache dynamic WordPress pages... for FREE!
Image optimization - Speed up the site by reduzing the size of the images! There's also a quick convesion to the next gen WebP format.
Database optimizations - including optimizing the database tables!
Private caching - caching for logged-in users and admin pages!
Page optimision is the other part of the LSCWP.
While Page caching usually works out of the box, Page optimsation requires testing as different WordPress sites are using a different themed and plugins. Some optimisation features may work great for your site, but others may brake it due to incompatibility issues.
It's quite possible that if you have two different WordPress web sites that a feature would work fine with the first site, but brake the second.
That's why, our best recommendation would be to start with a very basic LiteSpeed cache config - when only the Page caching options are enabled, then go through the Page optimisation options and test which work fine with your own site.
We can provide you with the basic config HERE.
You can download it (Right click and Save As... to your local computer), and import it into LiteSpeed Cache via:
LiteSpeed Cache >> Toolbox >>  Import/Export >> Choose File and Import:
The config also includes pre-configured Object Cache.
To use it:
2) Change the Host in: LiteSpeed Cache >> Cache >>  Object:
This has all the basics to get you going and speed up your WordPress, as well as reduce the resource usage generated by the site.
You should be able to see the difference straight away, but in case you need to verify LiteSpeed cache is working, click here.
To improve your site score on tools such as the Google's PageSpeed Insights and GTMetrix, you'll need to use the LiteSpeed Cache image optimization feature as well as look into the Page Optimisation section >> CSS Settings and JS Settings mostly.
Going forward, we can recommend checking the official LiteSpeed Cache documentation here, as well as - TESTING, TESTING and TESTING and making sure the selected feature/optimization works well with your own WordPress web site.
