That's because the whole premise of your benchmark relies on a workload that
yield()s itself to the eyeballs on most graphic card combinations when using
glxgears. Your test remains a test of sched_yield in the presence of your
workloads rather than anything else. If people like ck2 it's because in the
real world with real workloads it is better, rather than on a yield() based
benchmark. Repeatedly the reports are that 3d apps and games in normal usage
under -ck are better than mainline and cfs.
