This might sound pedantic, but is ext2 on the first half of your hard disk and reiserfs on the second half? If so, that could skew your results. Try putting the reiserfs in the first half of the disk and see if that makes a difference. See http://www.coker.com.au/bonnie++/zcav/ for why. -- #ozone/algorithm - trust.in.love.to.save
