Hello: I'm seeing some strangeness and want some insight. Case #1: I have 5 disks on my system and each is exported to a iSCSI initiator. When I run IOMeter tool, I see CPU util of about 80% of my CPU for Seq-Read operations. Case #2: If I bundle these 5 disks as Raid5, the performance is 20% lower as compared to above case but the CPU util is only 30% for Seq Read operations (as compared to 80% in case #1) Can someone shed some light on this - why would CPU be lower in #2 (I'm using 2.6.27 kernel in both cases)?
