I've never seen those last three, but it's been a few years since I bothered with 'top' in Linux. System performance is a notoriously difficult thing to measure and understand... user = amount of time the system is running userland code system = amount of time the system is running kernel code nice = I've never really understood this one idle = amount of time the system is doing nothing wait = amount of time the system is waiting for available CPU cycles Or something like that. -- OCLUG general discussion list [email protected] http://oclug.on.ca/mailman/listinfo/oclug
