I observed what I thought was a similar problem but found that I was
actually hitting the physical disks much harder/more efficiently ... I
found that I had some spindles with pretty deep queue depths. When I sat
back and actually measured, I found that my throughput had substantially
increased, moving the bottleneck to the disks. What does iostats tell you?
