Salem,
you really have to give more information. With the few lines you
provide, it is nearly impossible to give hints. It could even be
normal that you do not see a speedup, e.g. if your system is very
small (less than a thousand atoms?). So please let us know about
that, and also give the exact command line(s) you used, and maybe
attach and mdp input file and/or an output log.
