I tested 2.6.24-rc1 on my x86_64 machine which has 2 quad-core processors. Comparing with 2.6.23, aim7 has about -30% regression. I did a bisect and found patch http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=b5869ce7f68b233ceb81465a7644be0d9a5f3dbb caused the issue.
kbuild/SPECjbb2000/SPECjbb2005 also has big regressions. On my another tigerton machine (4 quad-core processors), SPECjbb2005 has more than -40% regression. I didn't do a bisect on such benchmark testing, but I suspect the root cause is like aim7's. -yanmin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
