This depends entirely on your own requirements. For example, if your
organization runs all Microsoft, then switching to Linux is probably a
mistake. What kind of support can you get from your IT department (or is
it just you)?

I find that administration of *NIX machines is easier, but that's just
because I have much more experience with them. I find them to be more
stable, reliable, and faster.

If your performance degrades after a 10-user load, I can think of a few
possibilities:

1. Your webapp simply requires lots of resources, and no amount of RAM
   will fix it: fix your app
2. Your webapp is poorly-written and no amount of RAM will fix it:
   fix your app
3. Your database is poorly optimized and a good DBA could help a lot:
   fix your db
4. Microsoft Windows is limiting your incoming connections due to
   licensing restrictions. I don't believe "Server" versions of MS
   Windows do this, but it's worth double-checking. The poor performance
   you observe in this case would be due to the throttling of incoming
   connections, not due to anything the webapp/db can control.

What are you doing with all that RAM? Huge caches?
