First and foremost, thanks for chiming in, Jonas. The more eyes on this matter the merrier. vmstat -i can provide interrupt rate and count in FreeBSD, e.g.: interrupt total rate irq1: atkbd0 227 0 irq6: fdc0 10 0 irq17: uhci1++ 4479741 10 cpu0: timer 814684046 2000 irq256: em0 17219212 42 cpu1: timer 814683722 2000 Total 1651066958 4053 > 2008/11/19 Jan Sebosik : > > [snip] > >> > >> Okay now I understand.
