Danga Interactive developed memcached to enhance the speed of,
a site which was already doing 20 million+ dynamic page views per day for 1
million users with a bunch of webservers and a bunch of database servers.
memcached dropped the database load to almost nothing, yielding faster page
load times for users, better resource utilization, and faster access to the
databases on a memcache miss.
memcached optimizes specific high-load serving applications that are designed
to take advantage of its versatile no-locking memory access system. Clients
are available in several different programming languages, to suit the needs
of the specific application. Traditionally this has been used in mod_perl
apps to avoid storing large chunks of data in Apache memory, and to share
this burden across several machines.
