i'm pleased to announce release -v13 of the CFS scheduler patchset.
The CFS patch against v2.6.22-rc1, v2.6.21.1 or v2.6.20.10 can be
downloaded from the usual place:
http://people.redhat.com/mingo/cfs-scheduler/
-v13 is a fixes-only release. It fixes a smaller accounting bug, so if
you saw small lags during desktop use under certain workloads then
please re-check that workload under -v13 too. It also tweaks SMP
load-balancing a bit. (Note: the load-balancing artifact reported by
Peter Williams is not a CFS-specific problem and he reproduced it in
v2.6.21 too. Nevertheless -v13 should be less prone to such artifacts.)
I know about no open CFS regression at the moment, so please re-test
-v13 and if you still see any problem please re-report it. Thanks!
Changes since -v12:
- small tweak: made the "fork flow" of reniced tasks zero-sum
- debugging update: /proc/<PID>/sched is now seqfile based and echoing
0 to it clears the maximum-tracking counters.
- more debugging counters
- small rounding fix to make the statistical average of rounding errors
zero
- scale both the runtime limit and the granularity on SMP too, and make
it dependent on HZ
- misc cleanups
As usual, any sort of feedback, bugreport, fix and suggestion is more
than welcome,
Ingo

Hi
Been testing this version of CFS from last an hour or so and still facing same
lag problems while browsing sites with heavy JS and or flash usage. Mouse
movement is pathetic and audio starts to skip. I haven't face this behavior
with CFS till v11.
'm not seeing this, do have a site or two as examples?
