While I can't comment on the technical/implementational details of Con's claim I definitely have to agree from a users POV. All my recent CPU intensive benchmarks show that both ck/sd and cfs are very decent scheduler and IMO superior to mainline for all _my_ usecases. In particular playing supertux while otherwise fully utilizing both CPUs on a dualcore works without any glitch and better than on mainline for both sd and cfs. For me the huge difference you have for sd to the others increases the likelyhood the glxgears benchmark does not measure scheduling of graphic but something else. Anyway, I'm still in the process of collecting data or more precisely until recently constantly refined what data to collect and how. I plan to provide new benchmark results on CPU intensive tasks in a couple of days.
