Terry Myers just emailed me suggesting that my server is overloaded due to the number of apache processes I currently have running and suggested I upgrade to litespeed and added more nodes. Im sorry but this is unacceptable, either he is unaware of the current SAN issues or is trying to divert from the current problems?
Here are some server stats taken right now: Can you honestly look at these and tell me my server is overloaded?
