Linux Scheduling Mechanism in 2.6.22?
I'm doing some kind of performance evaluation using two different vanilla Linux kernels, 2.6.22
and 开发者_StackOverflow2.6.31
, since I assume each of them uses a different scheduling mechanism: 2.6.22
uses the old O(1) scheduler, whilst 2.6.31
adopts the CFS. Could anybody confirm the correction of this assumption?
It is in linux-2.6.23 introduced the CFS ( http://kernelnewbies.org/Linux_2_6_23#head-f3a847a5aace97932f838027c93121321a6499e7 ) But the later kernel would have patches for it. IMHO, you could try a newer kernel if you want to do profiling.
