The above should go twice on fast on a dual. I have a PL dual 800. Believe it or not, I'm not a unix geek, so the terminal stuff gets lost on me. I'm happy to run this, but what should I be looking at for a result output and what are you comparing it to? Laurie -- AOL IM/iChat: cubeownernyc http://www.cubeowner.com Home of The Mac Cube FAQ!
