Linux compiled installation memcached

Memcached is a high-performance distributed memory object caching system for dynamic Web applications to mitigate database load.

It improves the speed of dynamic, database-driven Web sites by caching data and objects in memory to reduce the number of times a database is read.

Memcached is based on a hashmap that stores key/value pairs. Its daemon (daemon) is written in C, but the client can

Written in any language and communicates with the daemon through the memcached protocol.
