You'll see it slowly drop to 0 over 10-15 seconds. Junior Hacker Project: add an instantaneous-CPU value (calculated by subtracting successive ki_runtime values) to the list of things top calculates and toggle it and weighted-CPU when pressing C. The toggling code is already there; it just toggles between two different weighted-cpu values at the moment. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
