!!! Overview
[{$pagename}] is a general-purpose distributed memory [caching system|Cache]. 

[{$pagename}] is often used to speed up dynamic database-driven [websites] by caching data and objects in [RAM] to reduce the number of times an external data source (such as a [database] or [API]) must be read. 

[{$pagename}] is free and [Open Source] software, licensed under the Revised [BSD] [license]. 

[{$pagename}] runs on [UNIX]-like operating systems (at least [Linux] and OS X) and on [Microsoft Windows] and depends on the libevent library.

[{$pagename}]'s [APIs] provide a very large [Hash] table distributed across multiple machines. When the table is full, subsequent inserts cause older data to be purged in [Least Recently Used] ([LRU]) order.

[{$pagename}] has no internal mechanism to [track misses|Cache miss] which may happen. There are some 3rd party applications such as mctop which can be used or if your operating system support Dtrace you can use dtrace script.
