It partly depends upon the version of the OS that you are running, your hardware, and your configuration. 2008 interrupts/sec is high, but not improbably so, for kern.hz>=1000, and not beyond the capabilities of today's average computer, although it may not be optimal for your workloads. So it may not actually be a problem with too many interrupts, but rather with some erroneous system accounting. This can happen, for example, if your computer is using some of the deeper power-saving C-states, but using them poorly, as for example in: http://lists.freebsd.org/pipermail/freebsd-current/2010-August/019383.html So you may want to examine, and perhaps adjust, your choice of kernel timers, kern.hz, and power-saving settings. Device polling can also be a factor, if you are using it. b. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[email protected]"
