kern.eventtimer.timer: HPETの時
vmstat -i
interrupt total rate
irq1: atkbd0 8 0
irq14: ata0 47 0
irq17: bge1 3097 0
irq20: hpet0 uhci0* 716723 79
Total 719875 79
last pid: 1561; load averages: 0.80, 0.72, 0.71 up 0+02:29:57 21:17:18
kern.eventtimer.timer=LAPICの時
vmstat -i
interrupt total rate
irq1: atkbd0 8 0
irq14: ata0 47 0
irq17: bge1 2120 0
irq20: hpet0 uhci0* 14605 4
cpu0:timer 211006 65
cpu1:timer 31944 9
Total 259730 80
last pid: 1397; load averages: 0.00, 0.00, 0.00 up 0+00:53:17 22:12:42
で、hint.hpet.0.allowed_irqs="0x00e00000"として
kern.eventtimer.timer: HPETの場合
vmstat -i
interrupt total rate
irq1: atkbd0 8 0
irq14: ata0 47 0
irq17: bge1 829 0
irq20: uhci0 ehci0+ 2727 2
irq21: hpet0 uhci1 166180 161
Total 169791 165
last pid: 1341; load averages: 0.47, 0.49, 0.41 up 0+00:19:43 09:14:22
となります。hint.hpet.0.allowed_irqs="0x00400000"でIRQ22を割り当てても
irq22: hpet0 uhci1 166180 161
となり、load もさほどかわりません。
