    Hi,

    Just some explanation about the mistake.

    I have put cat /proc/pid/status instead of /proc/pid/smaps.

    So I was testing the /proc/pid/status and not the /proc/pid/smaps.

    Now I am testing with /proc/pid/smaps and the values are showing that
    the old one is faster than the new one. So I will keep using the old
    smaps version.

    Any suggestion???

    BR,

    Mauricio Lin.
