EAccelerator
eAccelerator was a PHP accelerator derived from the MMCache extension for the PHP programming language. eAccelerator provides a bytecode cache. eAccelerator is open source and thereby free to use and distribute. Old and unmaintained versions also provided an encoder. Every time a PHP script is accessed, PHP usually parses and compiles scripts to bytecode. Once installed, eAccelerator optimizes the compiled bytecode and caches this to shared memory or disk or both. Upon subsequent accesses to a script, eAccelerator will access cached bytecode if it is available instead of the script being compiled. This avoids the performance overhead of repeated parsing and compilation. Previous eAccelerator versions also provided functions for use in PHP scripts that allow access to shared memory, automatic web (content) caching, and other related tasks. These were removed as of version 0.9.6rc1. Old eAccelerator versions had an encoder component that creates a file that cannot be as easil ...

Alternative PHP Cache
This is a list of PHP accelerators. Alternative PHP Cache (APC) Alternative PHP Cache is a free and open (PHP license) framework that caches the output of the PHP bytecode compiler in shared memory, thus reducing parsing and disk I/O overhead for later requests; and a shared memory cache for user data. For an application consisting of a large source code base such as Drupal, a 3x increase in page generation speed is possible as a result. It has been used at Facebook and has a mature codebase thanks to numerous contributors, including Facebook itself. APC was originally scheduled for inclusion into the PHP core no later than PHP 6. While multiple accelerator projects were considered desirable, the focus has since moved to Optimizer Plus, and, later, Zend OPcache that is included in the core distribution as of PHP 5.5. Since March 2013, a beta version of APCu (APC User Cache) is available, in which all opcode caching abilities have been removed to support user caches in share ...
