Memcached Server simplifies development by providing a ready-to-run version of memacached, now you can manage the memcached service easily (start, stop, restart, launch at login, etc.). Memcached is a general-purpose distributed memory caching system. It is often used to speed up dynamic database-driven websites by caching data and objects in RAM to reduce the number of times an external data source (such as a database or API) must be read. ( Memcached: https://www.memcached.org/ ) If you are developing web applications that utilize memcached, Memcached Server is for you! Note: Memcached listens on port 11211 by default.
