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.
Using $_SERVER['PHP_SELF'] instead of $PHP_SELF in encoder.php and mmcache_password.php. Virtualhost support was improved. You can start mmcache with "mmcache.enable=0" and enable it only for some virtual hosts or directories. ZE2 compatibility was improved (tested with php5-200307290730). Some serios bugs were fixed.
