They could possibly even go in 2.6.13. I haven't really done performance testing because it is difficult to get real workloads going that really stress these things. There are small improvements on things like tbench on bigger systems, but nothing greatly interesting. I think on real workloads, things could get more interesting. Actually, it would be interesting to know how these go on the _really_ big systems, and whether lock and cacheline contention in the scheduler is still a problem for them. -- SUSE Labs, Novell Inc.
