I can get 0.33ms latency with the regual kernel, with a good config. But it still outperforms the regular kernel, according to Con Kolivas benchmarks, so if you want the absolutely lowest latency, go for it.

Seems to perform at bit better aswell in other areas, according to this article !Edited 2011-08-16 17:14 UTC Tue, 16 Aug 2011 17:13:00 GMT donotreply@osnews.com (ParadoxUncreated) Comments Comment by graudeejs http://www.osnews.com/thread?485323 http://www.osnews.com/thread?485323 Pretty brain fucked name for a scheduler Tue, 16 Aug 2011 17:44:00 GMT donotreply@osnews.com (graudeejs) Comments RE: Comment by graudeejs http://www.osnews.com/thread?485331 http://www.osnews.com/thread?485331 Perhaps it's coded in BF ?

It's coded in C - as is the rest of the Linux kernel (well, aside any ASM dotted about)

AFAIK there's no way to embed BF code into C so I'm not even sure you could have kernel elements written in BFEdited 2011-08-16 19:13 UTC Tue, 16 Aug 2011 19:10:00 GMT donotreply@osnews.com (Laurence) Comments name http://www.osnews.com/thread?485373 http://www.osnews.com/thread?485373 Seems like he is loving my brain.

I think it might be a maintenance issue but I feel this could be an opportunity for some sort of plugin system for the kernel similar to drivers. There might be other areas as well like memory management where it could benefit.

No, it's not (mainly) a maintenance issue, it's a policy choice: Linus wants to have a good "all-purpose" scheduler, not several special-purpose schedulers..

Of course, not everybody agree with him as shown by CK's BFS. Note that even if you don't use BFS, its existence had a nice side effect: it improved Linux, as it helped find a bug in the stock scheduler.
