The connection pool under Admin CP -> Actions -> Real-Time Stats -> External Application will occasionally show all available connections in use when the load skyrockets. Max Connections is currently set at 150. I have had it set as high as 300. I lowered it because it seemed that the higher the setting the higher server load.

If EAProc WaitQ stays 0, there is no need to increase Max Connections (use with care). 35 is the default. bump to 50, or 100 if needed (environment variable PHP_LSAPI_CHILDREN needs to match it). in your case, pls lower to 100.

when server load skyrockets, what takes most cpu cycle in 'top'?
