Hi Peter I just download the lastest ltp from http://sourceforge.net/projects/ltp/files/LTP%20Source/ltp-20130503/ and do cgroup benchmark tests on our SB-EP machine with 2S*8CORE*2SMT, 64G memory. Following is my testing procedures: 1. tar -xvf ltp-full-20130503.tar 2. cd ltp-full-20130503 3. ./configure prefix=/mnt/ltp && make -j32 && sudo make install 4. cd /mnt/ltp # create general testcase named cgroup_fj 5. echo -e "cgroup_fj run_cgroup_test_fj.sh" > runtest/cgroup # we only test cpuset/cpu/cpuacct cgroup benchmark cases, here is my cgroup_fj_testcases.sh 6. [changlox@lkp-sb03 bin]$ cat testcases/bin/cgroup_fj_testcases.sh stress 2 2 1 1 1 stress 4 2 1 1 1 stress 5 2 1 1 1 stress 2 1 1 1 2 stress 2 1 1 2 1 stress 2 1 1 2 2 stress 2 1 1 2 3 stress 2 1 2 1 1 stress 2 1 2 1 2 stress 2 1 2 1 3 stress 2 1 2 2 1 stress 2 1 2 2 2 stress 4 1 1 1 2 stress 4 1 2 1 1 stress 4 1 2 1 2 stress 4 1 2 1 3 stress 5 1 1 1 2 stress 5 1 1 2 1 stress 5 1 1 2 2 stress 5 1 1 2 3 stress 5 1 2 1 1 stress 5 1 2 1 2 stress 5 1 2 1 3 stress 5 1 2 2 1 stress 5 1 2 2 2 # run test 7. sudo ./runltp -p -l /tmp/cgroup.results.log -d /tmp -o /tmp/cgroup.log -f cgroup my test results: 3.10-rc1 patch1-7 patch1-8 duration=764 duration=754 duration=750 duration=764 duration=754 duration=751 duration=763 duration=755 duration=751 duration means the seconds of testing cost.
