What is Turck MMCache?
Turck MMCache is a free open source PHP accelerator, optimizer, encoder and dynamic content cache for PHP. 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 to speed up execution of PHP scripts. Turck MMCache typically reduces server load and increases the speed of your PHP code by 1-10 times.
Turck MMCache stores compiled PHP scripts in shared memory and execute code directly from it. It creates locks only for short time while search compiled PHP script in the cache, so one script can be executed simultaneously by several engines.
Configuration Options
mmcache.shm_size
The amount of shared memory (in megabytes) that Turck MMCache will use. "0" means OS default. Default value is "0".
mmcache.cache_dir
The directory that is used for disk cache. Turck MMCache stores precompiled code, session data, content and user entries here. The same data can be stored in shared memory also (for more quick access). Default value is "/tmp/mmcache".
mmcache.enable
Enables or disables Turck MMCache. Should be "1" for enabling or "0" for disabling. Default value is "0".
mmcache.optimizer
Enables or disables internal peephole optimizer which may speed up code execution. Should be "1" for enabling or "0" for disabling. Default value is "1".
mmcache.debug
Enables or disables debug logging. Should be "1" for enabling or "0" for disabling. Default value is "0".
mmcache.check_mtime
Enables or disables PHP file modification checking. Should be "1" for enabling or "0" for disabling. You should set it to "1" if you want to recompile PHP files after modification. Default value is "1".
mmcache.filter
Determine which PHP files must be cached. You may specify the number of patterns (for example "*.php *.phtml") which specifies to cache or not to cache. If pattern starts with the character "!", it means to ignore files which are matched by the following pattern. Default value is "" that means - all PHP scripts will be cached.
mmcache.shm_max
Disables putting large values into shared memory by "mmcache_put()" function. It indicates the largest allowed size in bytes (10240, 10K, 1M). The "0" disables the limit. Default value is "0".
mmcache.shm_ttl
When MMCache fails to get shared memory for new script it removes all scripts which were not accessed at last "shm_ttl" seconds from shared memory. Default value is "0" that means - don't remove any files from shared memory.
mmcache.shm_prune_period
When MMCache fails to get shared memory for new script it tryes to remove old script if the previous try was made more then "shm_prune_period" seconds ago. Default value is "0" that means - don't try to remove any files from shared memory.
mmcache.shm_only
Enables or disables caching of compiled scripts on disk. It has no effect on session data and content caching. Default value is "0" that means - use disk and shared memory for caching.
mmcache.compress
Enables or disables cached content compression. Default value is "1" that means enable compression.
mmcache.keys
mmcache.sessions
mmcache.content
Determine where keys, session data and content will be cached. The possible values are:
"shm_and_disk" - cache data in shared memory and on disk (default value)
"shm" - cache data in shared memory or on disk if shared memory is full or data size greater then "mmcache.shm_max"
"shm_only" - cache data in shared memory
"disk_only" - cache data on disk
"none" - don't cache data
