PHP Accelerators
PHP Accelerators/Cachers will boost the performance of your PHP applications, by caching the compiled form of php scripts to avoid the overhead of parsing and compiling the code every time the page is loaded. A PHP accelerator typically reduces server load and increases the speed of your PHP code by 1-10 times. Normally you will install these in the form of a php extension.

“eAccelerator was born in December 2004 as a fork of the Turck MMCache project. Turck MMCache was created by Dmitry Stogov and much of the eAccelerator code is still based on his work. eAccelerator also contains a PHP encoder and loader. The latest release, 0.9.5, supports PHP 4 and all PHP 5 releases including 5.2. In older releases, the encoder will only work with PHP versions from the 4.x.x branch. eAccelerator will not work with any other versions of PHP.â€

3. XCache – http://trac.lighttpd.net/xcache/
“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.â€
