It looks like "ksoftirqd_CPU0" eats up all the CPU processing with a traffic of just 55 Mbps !! ( it's not my hardware... I'm using a Dual Xeon 2Ghz and with kernel 2.4.9 it could handle easily 85 Mbps ) 'vmstat 1' output: r b w swpd free buff cache si so bi bo in cs us sy id 0 0 1 0 1988284 2528 17052 0 0 0 0 826 352 0 16 84 0 0 0 0 1988264 2528 17052 0 0 0 0 17486 51 0 25 75 0 0 1 0 1988264 2528 17052 0 0 0 0 17661 29 0 25 75 0 0 1 0 1988264 2528 17052 0 0 0 0 17424 32 0 25 75 0 0 1 0 1988264 2528 17052 0 0 0 0 17428 42 0 25 75 0 0 1 0 1988264 2528 17052 0 0 0 0 17572 46 0 25 75 ( with 2.4.9 interrupt rate was over 50.000 !! ) lsmod output: Module Size Used by Tainted: P ipchains 46184 162 e1000 57508 2 raid1 15780 2 aic7xxx 125440 6 sd_mod 12896 12 scsi_mod 112272 2 [aic7xxx sd_mod] ( I don't rules loaded that could impact performance ) Anybody ?
