I just ran bonnie on a Dual-Core 3.4ghz machine w 2GB RAM and 2x120GB Seagate SATA HDD on 3Ware 8006 set as RAID 1 mirror. Ext3 FS. Second Machine is Intel 2.6ghz HT w/2GB RAM and 2X120GB Seagate SATA HDD - no 3Ware, no RAID. EXT 3. /usr/local/bonnie/sbin/bonnie++ -d /bk1/iotest -s 10g -n 0 -b -f -u mail >output.txt Version 1.03 ------Output------ --Input- --Block-- --Rewrite-- --Block-- --Seeks- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP 3wRAID1 10G 35903 12 22456 5 58840 5 175.5 0 SATA 10G 30154 16 14094 5 42492 5 96.0 0 neither machine has any notable load 0.00 to 0.01 as they are both idle at the moment. This doesn't seem stellar by what I'm seeing on the 9550 thread, but overall, without any tweaking, does this look reasonable? Mike
