A quick call to 3ware and they told me to increase vfs.read_max from 8 to 256. That helped. I'm now seeing 4x performance on a four-drive array vs a single drive. Additionally, Ivan was right about the database being too small. iostat showed no disk activity after the initial run, as everything was cached in memory. -- Milo Hyson CyberLife Labs
