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. http://btrfs.boxacle.net/repository/raid/history/History.html 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/. Steve
