    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

    # 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.
