关于linux用作路由器，打性能数据
大家好，我测试一台ATOM的机器用作ip forward路由器时候的性能： 在测试仪向ATOM发（64bytes包大小）数据流的时候，在ATOM上的机器用top命令显示 如下：top - 22:52:31 up 45 min,1 user,load average: 1.05, 0.57, 0.36
Tasks: 119 total, 3 running, 116 sleeping, 0 stopped, 0 zombie
Cpu0:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
Cpu1:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
Cpu2:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
Cpu3:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
Cpu4:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
Cpu5:0.0%us,0.0%sy,0.0%ni,0.0%id,0.0%wa,0.0%hi,100.0%si,0.0%st
Cpu6:0.0%us,0.0%sy,0.0%ni,0.0%id,0.0%wa,0.0%hi,100.0%si,0.0%st
Cpu7:0.0%us,0.0%sy,0.0%ni,100.0%id,0.0%wa,0.0%hi,0.0%si,0.0%st
可以看出CPU5和CPU6的使用率为100%，而其他 CPU使用率为0%,而且所有的CPU的消耗都集中在"si"软中断上面。
而且两个CPU不是固定的，比方说，我打了3次性能 ，这次是cpu5和cpu6 ，下次可能是cpu1 cpu3 ,下下次可能 是cpu4 cpu5.....
请问，谁有比较好的办法去均衡这个软中断到其他 Cpu呢？
谢谢 irqbalance ? 我已经开了irqbalance了，但是效果不明显，基本上也是这样。回复 2# q1208c

或许, 网卡的队列也要多个了 :em17:
