Thanks for running this. I too remember SDET, but I won't claim to be old. :)
We were doing some more analysis on the multi-queue scheduler and noticed that performance has regressed since posting preliminary numbers with the 2.4.0-test10 kernel. After comparing the code, it looks like I have over-engineered for the worst case of lock contention. This was done at the expense of the normal case. I'm currently working on this situation and expect to have a new patch out in the not too distant future.
I expect the numbers will get better. -- Mike Kravetz mkravetz@sequent.com IBM Linux Technology Center - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
