IOMeter with one worker atop each of 4 SRP-imported/multipathed (round-robin) drives and a queue depth of 64. I'm seeing ~450K random 4KB write IOPS. With two HCA's, both running the latest firmware (as of Friday), I see two cores on one NUMA node totally pegged/consumed, and affinity is set on the Dynamo's to avoid these cores... so something is either polling or interrupt handling on these. I'm running the latest 2.3RC4 WinOF.
