The Completely Fair Scheduler's Impact On Games 315
eldavojohn writes "We've heard a bit about the completely fair scheduler previously, but now Kernel Trap looks at the implications this new scheduler has for 3D games in Linux. Linus Torvalds noted, 'I don't think any scheduler is perfect, and almost all of the time, the RightAnswer(tm) ends up being not one or the other, but somewhere in between. But at the same time, no technical decision is ever written in stone. It's all a balancing act. I've replaced the scheduler before, I'm 100% sure we'll replace it again. Schedulers are actually not at all that important in the end: they are a very very small detail in the kernel.' The posts that follow the brief article, reveal that Linus seems quite confident that he made the right choice in his decision to merge CFS with the Linux kernel. One thing's for certain, gaming on Linux can't suffer any more setbacks or it may be many years before we see FOSS games rival the commercial world."

And then the news post here, says "Linux cannot suffer any setbacks in gaming". I think you'll find that compared to the original scheduler, CFS pretty much rocks for gaming. As much or less than SD, who the fuck cares?
It's better than the original scheduler, so where's the setback?
If it's not as good as SD, oh well, cry me a river. I don't agree with Linus' "there is no maintainer" idea, but more the concept that CFS removes more lines from the kernel than it replaces, and does a better job, whereas SD adds complexity for roughly the same effect. What could be a perfectly good technical reason in previous LKML posts got turned into politiking.
Difference between SD and CFS.. fractions of a frame per second. WOW. That really means Linus made the wrong decision! The impact on games, where 1/500th of a second really MAKES A DIFFERENCE is too high! Put the old scheduler back you fucking crazy-ass Finn!!
