Memcached

Dependencies

• libevent, http://www.monkey.org/~provos/libevent/ (libevent-dev)

Environment

Linux

If using Linux, you need a kernel with epoll. Sure, libevent will work with normal select, but it sucks.

epoll isn't in Linux 2.4, but there's a backport at:

http://www.xmailserver.org/linux-patches/nio-improve.html

You want the epoll-lt patch (level-triggered).

Mac OS X

If you're using MacOS, you'll want libevent 1.1 or higher to deal with a kqueue bug.

Also, be warned that the -k (mlockall) option to memcached might be dangerous when using a large cache. Just make sure the memcached machines don't swap. memcached does non-blocking network I/O, but not disk. (it should never go to disk, or you've lost the whole point of it)
