--- Comment #11 from Mel Gorman
Phoronix repeated the tests with the released openSUSE 42.1:

Sadly, openSUSE 42.1 is amongst the slowest compared distros, especially in anything disk-intensive.
As I understand, they used XFS for tests this time on openSUSE.
openSUSE LEAP shipped with a version of systemd that puts processes into cgroup controllers in some cases. It's possible that Phoronix were impacted. The blkio controller issue was removed before ship but processes may still added to memory and cpuacct controllers. It's known that the cpuacct controller caused a 27% regression on one particular scheduler microbenchmark and also impacted a number of other workloads. It's fixed in SLE but the same package has yet to be pushed to openSUSE LEAP. It needs to be eliminated as a potential problem. A workaround is to edit /usr/lib/systemd/system/user@.service and set Delegate=no -- You are receiving this mail because: You are on the CC list for the bug.
