(these are just made >up examples) Yes but most of the RISC chips although slower in Hz should be capable of running 'real' instructions faster. I also wasn't aware of an 8MB cache Intel chop being available, at least the RISC chips have decently sized caches. I accept they're not cheap. >Second, UNIX runs on a much faster kernel than NT, which offsets the >cost somewhat. >The cost of administrating NT is less, but the remote admin tools for >UNIX offset this also, in my opinion. I'm sorry but I think that is totally spheroids. A few months back four of us were running a little over 400 production servers for one of the utilities, there was 4 people running the Novell servers, about 300, and over 20 to run 200(ish) NT servers. Another 400 NT servers were planned and the NT team was expected to double. >Lastly, while both OSs support multiple processors, there was a white >paper published a while ago (sorry, I can't give you a link), that >described the benefits of installing multiple processors on both OSs. >On UNIX, they noticed an 80% increase in performance for adding a second >processor and every processor after that, while on NT, they only got 50% >for each.

In my experience with NT you get increases up to 3 processors, the fourth one just seems to give morale support to the others. >One other thing, I really hate the fact that on NT, if you change >something on the system (add a new NIC card, etc) I had to reinstall the >latest service pack before I rebooted or the machine wouldn't come back >up and the emergency disks did me absolutely no good.
