I tested this patchset against a slightly patched 2.6.25-rc2-mm1 (compile-failure fix and a memoryless-related bug that is fixed in git-x86#testing). > These are the range of performance losses/gains when running against > 2.6.24-rc4-mm1. The set and these machines are a mix of i386, x86_64 and > ppc64 both NUMA and non-NUMA. > Against 2.6.25-rc5-mm1, the results are loss to gain Total CPU time on Kernbench: -0.23% 1.04% Elapsed time on Kernbench: -0.69% 3.86% page_test from aim9: -3.74% 5.72% brk_test from aim9: -7.37% 10.98% fork_test from aim9: -3.52% 3.17% exec_test from aim9: -2.78% 2.34% TBench: -1.93% 2.96% Hackbench was similarly variable but most machines showed little or no difference. As before, whether the changes are a performance win/loss depends on the machine but the majority of results showed little difference. > loss to gain > Total CPU time on Kernbench: -0.86% to 1.13% > Elapsed time on Kernbench: -0.79% to 0.76% > page_test from aim9: -4.37% to 0.79% > brk_test from aim9: -0.71% to 4.07% > fork_test from aim9: -1.84% to 4.60% > exec_test from aim9: -0.71% to 1.08% > -- Mel Gorman Part-time Phd Student Linux Technology Center University of Limerick IBM Dublin Software Lab -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
