ooops. Yeah, ignore the 85MB values.
Here it is again, using "bonnie -s 256" on my 128MB P2-400 w/raid0 (2 IDE):
Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done...
-------Sequential Output-------- ---Sequential Input-- --Random--

Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU
256 17374 95.5 32681 33.2 10706 24.3 15683 68.4 23710 24.3 214.6 1.8
Those numbers look very believable to me. Not bad for mere IDE devices.
A caveat for bonnie: on an ideal system, with inifinitely-fast I/O,
the %CPU numbers should all be 100%. Anything less means the CPU
is being held up waiting for I/O.
Thus, %CPU does not give any meaningful representation of actual
*usage* of the CPU (as in, how much processing was needed to do everything).
Cheers
