ClusterHQ's tests were unable to detect a difference between the platforms, with the exception of SELinux where performance was degraded unless xattr=sa was set. The code bases are almost identical, so performance differences tend to be caused by external factors and/or compatibility shims. There are also cases where one platform has a performance improvement before the others because the releases and porting are not done in lock step.
