i personally like shimon's st.d... it exercises a disk very thoroughly, so if you want to benchmark - and, of course, have plenty of time for the box to run the benchmark - st.d is the choice since you got your free-of-charge(tm) burn in of the disk subsystem with it. what it basically does is simulating a nonlinear load behaviour like you got in a multi-client or large amount of concurrent i/o processes environment and i like it a lot. welps, i won't argue about the command line parameters - just see for yourself ;-) http://www.simon-shapiro.org/st_d/index.html /k Greg Lehey(grog@lemis.com)@Sun, Feb 13, 2000 at 03:16:50PM +1030: > On Friday, 11 February 2000 at 10:49:24 +0100, Christoph Kukulies wrote: > > PIII/500, 128 MB > > > > I'm wondering if this is trustable: > > > >> bonnie -s 400 > > File './Bonnie.14321', size: 419430400 > > Writing with putc()...done > > Rewriting...done > > Writing intelligently...done > > Reading with getc()...done > > Reading intelligently...done > > Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done... > > -------Sequential Output-------- ---Sequential Input-- --Random-- > > -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- > > Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU /sec %CPU > > 400 20015 73.7 18369 22.9 6750 12.6 22308 81.5 22467 26.0 93.8 1.0 > > ^^^^ > > ? > > > > > > wdc0 at 0x1f0-0x1f7 irq 14 flags 0xa0ff on isa > > wdc0: unit 0 (wd0): <IBM-DPTA-372050>, DMA, 32-bit, multi-block-16 > > wd0: 19574MB (40088160 sectors), 39770 cyls, 16 heads, 63 S/T, 512 B/S > > There are lies, damn lies, and statistics.
