I'd like to dispel a few issues I have with this thread.
First things first, this was not started to cause a debate between Linux users, Unix users, and Windows users.
Second, not a single one of you is answering his question for a WINDOWS machine, which was originally the entire point. I will do so shortly.
Third, you Unix users are ok. I respect your knowledge of that OS. Don't force it on me. Same goes for you Linux users. It doesn't matter who's machine outperforms another, because in the great big world, nobody cares what your stuff is served from, they just want it now. My machine isn't sitting on your desk 24/7, so don't complain about what I use for an OS. I can probably do things with my Windows 2000 Advanced Server machine that you Linux users can only dream about, because let's face it. Less than half of you actually know how to write your own kernel, and the ones that do don't bother screaming at everyone because they know the OS is doing for them what it needs to. Get over your high and mighty attitude, solve your own problems, and leave everyone else alone. If you have something CONSTRUCTIVE to say, do so. That is all.
As for the real answer to this question, which I doubt will be read by anyone who needs to read it, I'll post that at the end of this thread.
