1) You can also try the ZM 1.25.0 performance patch: http://www.zoneminder.com/forums/viewtopic.php?f=9&t=17652 . +1 this is the best patch ever for zoneminder. I don't know why it's not already in the mainline because it has been tested for a long time by many users. To the author of zoneminder ...

This is a very very good patch.

I don't know if the original author of zoneminder is aware of it but it would benefit zoneminder to include it in the official source code !
