phil hunt enlightened us with: > If a program is too slow to respond isn't that about "system time"?
Not by definition. Could be anything. If it's slow to respond due to a slow harddisk, then you're right. If it's slow to respond due to not putting the I/O and the GUI main loop in different threads, then it's not about "system time". > What does "CPU time" mean again? The time the CPU takes to run (part of) a program. And this means the time the CPU actually spends on running that program, and not some other piece of software.

Not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?
