I tested with an external journal on a hardware (8506-2) RAID1 of 2 WD Raptor drives, and it made no difference. What *did* make a difference was using XFS (via the centosplus kernel), but I didn't trust that in production. I ended up going to software RAID, which got good local speeds. I'm discovering now, though, that the NFS performance sucks. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
