Turck MMCache is a PHP Accelerator, Optimizer and Encoder. It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated. Also it uses some optimizations for speed up of PHP scripts execution. Turck MMCache typically reduces server load and increases the speed of your PHP code by 1-10 times. It has been tested with PHP 4.1.0 - 4.3.2 under Linux and Windows with Apache 1.3 and 2.0.
User cache was extended to disk. New configuration directives "mmcache.filter", "mmcache.shm_max", "mmcache.shm_ttl" and "mmcache.shm_prune_period" were implemented. Now MMCache session handlers can be installed in php.ini file thorough configuration directive "session.save_handler=mmcache" (PHP 4.2.0 or above is required). The oldest PHP versions should call "mmcache_set_session_handlers()" function. Optimizer bug fixed. Tested with PHP 4.3.2.
