.Optimize mySQL memory usage ? 41MB threads ??

[Jon Shoberg]

I have a small PHP website that gets a fair amount of traffic.  It's a
simple layout with two tables. I average about 50 concurrently open
apache sessions and 40 open mysql connections.  I am calling for
persistent connections from the mySQL/PHP API.


But here is the kicker.  Each mySQL thread takes about 41mb!! :(  Can
anyone point me to resources on optimizing mySQL's memory usage under a
moderate/heavy load?

Thanks
Jon
