Lazy - mea culpa, though I'm using mutt so it isn't even hard. The question still stands: the test results are only valid if CPU was at 100% in all configurations. This is the reason I generally prefer it when people report throughput divided by CPU (power would be good too but it still isn't easy for people to get that number). -- MST
