The CPU time during the 'polling' is charged to interrupt, even though it occurs during softclock. That's why you see 0 interrupts, but high CPU usage in interrupt. Did u try lowering the 'register' access? --don _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
