I need to quantify the additional CPU load that RAID-0 adds (vs. the

'dd if=/dev/zero of=/dev/md?" should do the trick, but I'm not sure how
to track the processor utilization during the run.

Any ideas?


top not good?


I'm hoping for something that can report the avergage load during the entire run. I don't want to sit there and watch it.

From a brief look a the man page, top doesn't seem to do this.
