The XCache is useful when your websites have page load time issue. I think we all were faced/are facing the same problem while browsing high traffic websites most times. Here is the solution for that by caching the already executed files and and uses the executed one when we recall the same from browser again.
XCache is a fast, stable PHP opcode cacher that has been proven and is now running on production servers under high load. It is tested (on linux) and supported on all of the latest PHP release branches such as PHP_5_1 PHP_5_2 PHP_5_3 PHP_5_4 PHP_5_5. ThreadSafe/Windows is also perfectly supported. XCache overcomes many of the problems found with other opcachers such as being able to run with new PHP versions.
XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduces server load.
