Memcached is a distributed caching system.
memcached (pronunciation: mem-cache-dee.) is a general-purpose distributed memory caching system that was originally developed byDanga Interactive for LiveJournal, but is now used by many other sites. It is often used to speed up dynamic database-driven websites by caching data and objects in memory to reduce the number of times the database must be read.
memcached is used by some of the most popular sites on the Internet including Facebook and applications such as mediawiki.
