It's saying of the CPU cycles that are being used, this is what it breaks down as. Since MySQL is a userland application, you'd expect the value of user to be quite high if that was only thing running on your system and it was under high load. You can infer how much CPU is being used from the line, but there are better and more accurate methods generally of getting that information especially with SMP systems. -- Adam Vande More _______________________________________________ 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"
