    Now I applyed the right patch and it perform in the same way. I have not
    the /proc sysctl and I had to reset again after cp /tmp/zero /dev/null.

    I set these settings and it continue to perform worse than the stock
    kernel _during_ cp file /dev/null where file is very long.

    Did you tried cp file /dev/null?
