Memcached in Production.

[Sara Sioux]

Well, I'm running on a FreeBSD platform, and I'm using two servers in my
pool.  One of them is defined with a public IP, the other is the
localhost IP.

Is there any way I can check how many connections are open?  Or begin to
diagnose how to improve the connection speeds?

Sara,

Are you running memcached on Linux?  If so, get the Linux bugfixes in
libevent-0.7c:

   http://www.monkey.org/~provos/libevent-0.7c.tar.gz

More than likely, that's your problem.  Rebuild and install that, then
rebuild and install memcached.

As for the PHP API, there are two.  Without experience with either, I'd
recommend the newer one, as its parsing seems a lot more
straight-forward:
