memcached 1.5.3 for Mac can be downloaded from our website for free. Memcached for Mac belongs to Developer Tools. This free Mac app was originally designed by Brad Fitzpatrick.
From the developer:
Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.
You may want to check out more Mac applications, such as DBExplorer 2, FastoNoSQL or BitNami Ruby Stack, which might be related to memcached.
