1. Introduction: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 write in any language and communicate with the daemon through the Memcached protocol

, Gopher, SSL and WAIS protocols. Unlike general proxy caching software, squid handles all client requests with a separate, modular, I/O-driven process. Squid caches the data elements in memory while also caching the results of DNS lookups, in addition to supporting non modular DNS queries that negatively cache failed requests. Squid supports SSL and supports access control. The maximum bandwidth savings a
