Did a quick bench of 9240-8i (IBM M1015). Why would it cause large CPU utilization when it has LSISAS2008 IOP PowerPC 440 @ 533MHz? I saw almost 25% on 4K random read at QD16. I realize this is not ROC LSISAS2108, but still, should it offload CPU?

@CT I will post extensive benches as promised later P67 is very fast though, hehe.
