If you are looking for a caching solution to speed up the website performance, XCache is one of the best options.
What is XCache, and what are its uses?
1. XCache accelerates the performance of PHP on servers by speeding up page loading.
2. XCache optimizes performance by eliminating the compilation time of PHP scripts by caching the compiled state of PHP scripts into the RAM and using the compiled version straight from the RAM.
3. This will increase the page generation time up to 5 times as it also optimizes many other aspects of PHP scripts and reduces server load.
How to Enable XCache via SSH
