There is one ratio that is a far better indicator than any of that fancy wait analysis stuff - the USR (User Satisfaction Ratio). I usually consider the system to be optimal if the USR is near 97% (the other 3% are chronic whiners anyway). Of course, this does not apply if the CEO is in that 3%. Any CEO waits are considered unacceptable.
