:>> :>> Dag-Erling Smorgrav - des@flood.ping.uio.no :> :> top is kinda cpu-heavy. Occassionally I'll use 's0<return>' just to :> watch the display go nuts, but beyond the laughs having a less then :> one second update time isn't all that useful for top. : :I think that depends on what you're looking at. I could imagine that :people look at other things besides the CPU time breakdown. I :personally think that it would be a useful thing to have. : :Greg Well, as I said, top can be very cpu-heavy, especially on machines with a lot of processes. So if you are going to allow < 1 second top the feature should be restricted to root. systat, vmstat, and iostat are not cpu-heavy and one could allow < 1 second operation with those programs without the root restriction, though I would impose a 1/10 second minimum. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
