"fuel"? It's the first (that I've seen) well described, reproducible test that includes a howto for retesting in this debate... Whether someone improves BFS (cpu jumping) or CFS (general performance) because of this post, we win. Great!
Edit:
And that's what happened (more or less) - in the first response:
But, I believe, that test suffers from one fatal flaw: Hyperthreading was enabled, and as far as I know BFS does not support hyperthreading. (Support means: know that that the two CPUs are really the same, rather than treat them as if they were two different physical CPUs.)
Ah yeah - sorry - I'm just deliberately ignoring the "official" benchmarks from Ingo and Con... At least until one of them publishes a benchmark that shows their own solution loses in some scenario ;)

[ 2.7 ms ] story [ 12.8 ms ] threadThis is about the choice of CPU scheduler in the linux kernel.
CFS: Completely Fair Scheduling, current default.
BFS: Brain Fuck Scheduler, written by the infamous Con Kolivas, see http://news.ycombinator.com/item?id=799147
EDIT: I know a language named similar but that's more like a for-fun project, not a serious one to the extent of replacing existing solutions
