Memcached is an open-source object caching program that speeds up your database performance by caching data in memory. It is very useful for dynamic websites that allow repeated PHP object calls to be cached in system memory. It stores data based on key-values for small arbitrary strings or objects. It offers a lot of features including, ease of use, sub-millisecond latency, multithreaded architecture, data partitioning, support for multiple languages, and many more.

Today we will show you how to improve the performance of your website with APC and memcached.
APC stands for Alternative PHP Cache and it is an open source solution if you like to speed-up your website. APC caches the output of compiled PHP code and stores the result in shared memory.
