Welcome to XCache

Description

XCache is a fast, stable ​PHP opcode cacher that has been tested and is now running on production servers under high load. It is tested (on linux) and supported on all of the latest ​PHP cvs branches such as PHP_4_3 PHP_4_4 PHP_5_0 PHP_5_1 PHP_5_2 HEAD(6.x). ThreadSafe/Windows is also supported. It overcomes a lot of problems that has been with other competing opcachers such as being able to be used with new ​PHP versions.
