Then I tested the patch on our 2P/4P core2 machines and 2P NHM, 2P WSM machines. Most of benchmark have no clear improvement or regression. The testing benchmarks is listed here. http://kernel-perf.sourceforge.net/about_tests.php But the following results worth to care: 1, netperf loopback testing has a little improvement. 2, hackbench process testing has about 10% regression on both Core2 machine 3, fio testing has about 10~20% regression on mmap rand read testing. on our raw mode JBOD that attached on NHM and WSM machine. The JBOD use We use "numactl --interleave all " to do fio testing. one of testing file as below: ============= [global] direct=0 ioengine=mmap size=8G bs=4k numjobs=1 loops=5 runtime=600
