No, but then _I_ didn't compare them. I _knew_ what I was talking about. Again, look up "sun phoenix". Played on a bunch of Suns at Sun headquarters in California. Using 10mbit ethernet as there was nothing faster at the time. Quit making numbers up. as far as my "poor state of analytical insight", it has produced a program that appears to do better than yours. You should also watch how you toss insults, as they often bounce back in your own lap if you can't produce something better than something you call "bad"...
