Re: Increase the degree of interactivity ULE scheduler

Maybe useful the following information:
This problem appears not to all architectures and types of CPU.
on the Russian forums

was a brute force to find out that:
there is a suspicion that:
- for AMD processors, this problem is not observed at all when the number of cores >= 2
- on all single-core is the problem
- only for some models with Intel >= 2 cores of the problem is not found

Perhaps, after all, avg_at_ rights (Subject: couple of sched_ule issues), that is not working
properly mechanism rebalancing and to determine the topology of CPU?
All converge, because my patch ( http://docs.freebsd.org/cgi/mid.cgi?20111022132817.35db5ccd )
for SMP systems just do respite for rebalancing, which eliminates the problem with interactivity ...

Thanks!
