90MB per process? wow. Can you look in the server logs to see which query is
taking all the time?
I know PHP has persistant and non-persistant connections. I don't know what
criteria it uses to determine when the connection can be closed. Do you know
what your server is doing?
Lastly, is there a lot of disk activity?
