Finally got around to going through latest data. Seems like we lost all
the random write performance gains. Creates are better, but total
regression on the random workload. Sequential reads seem to have
dropped as well.

Results are uploading now.

These are for RAID only as single disk system still having issues
completing btrfs runs. Also, missing oprofile duw to oprofile causing
an NMI and killing the system.

Chris, this was built on 7/6, but I see no new changes sine 7/2/.
