Turck MMCache is a PHP Accelerator, Optimizer, Encoder and Dynamic Content Cache. 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.
Content compression was reimplemented. Bug in runtime class/function declaration was fixed. Optimization for functions extension_loaded(), function_exists(), is_callable(), defined() was implemented. Optimization of reset() functuin was fixed. mmcache_get() and mmcache_put() now support for stdClass objects.
