Mobile test results using GTMetrix test for LiteSpeed Cache vs. WP Rocket

In the AMP test results, WP Rocket fared well compared to desktop. But it is not an accurate measure, as caching doesn’t have much effect on AMP. But I would like to test the performance of AMP pages using page speed test tools. The results are great.

Here also, TTFB 318% faster in LiteSpeed Cache compared to WP Rocket. It is primarily because of QUIC.cloud CDN. The fully loaded time is 24% faster than WP Rocket. Compared to the desktop pages, WP Rocket has improved in the AMP test results.

LiteSpeed Cache – Free

This plugin is free by itself. But to use page caching you need a LiteSpeed Server. The reason being caching mechanism done by the cache engine on the server. Some hosting services provide this type of server.

If you don’t have it then you can use the Free QUIC.cloud CDN, which provides a LiteSpeed server. The cache usage is based on a pro-rata basis. For small sites a starting price of $5 is sufficient.

Ecommerce – LiteSpeed Cache vs. WP Rocket

The LiteSpeed cache solution allows a cache of dynamic pages using its server engine technology. You need to enable the ESI (Edge Side Includes) module to make this happen. Product pages and blocks of code can be cached using this method. Holes are punched in the public pages and shopping cart data is served using dynamic cache. Without lose of any security.

WP Rocket supports caching of shopping pages using WooCommerce technology. But dynamic caching of carts, check-out pages, and private pages is not possible.

Installation

The LiteSpeed Cache plugin has 2+ million installations, according to the WordPress plugin repository. It is by far one of the most used cache plugins. But the configuration is a little difficult and needs some technical expertise. But QUIC.cloud settings are far easier. You benefit for the hard-work done.

Another important LiteSpeed Cache vs. WP Rocket comparison feature is the number of users.

WP Rocket settings are far easier to configure than LiteSpeed Cache. But for advanced settings like critical CSS generation, font cache you need to be a better user of WordPress. It works on all types of servers, which is another pro of WP Rocket. The number of WP Rocket installations is also around 2+ million.

Recommendation

I recommend to install LiteSpeed Cache plugin with QUIC.cloud. Though WP Rocket is more popular and easy to configure, it doesn’t fit all needs. You need extra plugins to do page caching, CSS and JS compatibility.

On the other side, if you can learn a few settings of LiteSpeed Cache and install it, it does wonders. The GTMetrix and PageSpeed Insights results show that LiteSpeed Cache scores a complete 100.

But if you have display and video ads, the game is altogether different. Then you need to do further benchmark tests.
