The chunk size was 32k (for 0 and 5), fs block size 4k and for RAID-5, in addition, partitions were formatted with "-R stride=8 -g 7936" (0 and 1 seemed insensitive to anything but block size). http://www.idiom.com/~tbyrd/softraid/index.html Celeron 500Mhz - 20Gb IDE Raid5 - linux-2.2.3 http://www-hpcc.astro.washington.edu/reschke/Linux_MD_Benchmarks/ http://www.acnc.com/benchmarks.html - list of tools http://www.ACNC.com/04_02.html hdparm http://www.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html bonnie old benchmark program http://www.textuality.com/bonnie/download.html bonnie++ updated bonnie to reflect modern hardware http://www.coker.com.au/bonnie++/ tiotest looks promising, still being developed http://www.icon.fi/~mak/tiotest/ http://www.iki.fi/miku/tiotest/tiotest-0.23.tar.gz iozone havent tried this, but www.iozone.org shows it can do pretty graphics, and also has a long feature list. mincore() madvise() dbench http://people.redhat.com/dledford/benchmark.html # # # end of file
