Well, since you said IIS I'm assuming you are talking HTTP requests rather than TTY sessions. There is a fair bit of data available on the internet that shows that a Linux/Apache combination can sustain many more concurrent http requests than a IIS/NT set up, all things being equal (many of these comparative studies are fairly dated though).

It's probably still true, but with memory prices at all time lows, (NT tended to be a lousy memory manager, XP, 2000 are better but like lot's of memory just the same) it matters less.

I'd double check that comment that "IIS out of the box can only handle 10 concurrent users ", and lastly be careful writing papers like that in an IIS shop, you may find yourself gnawing at your leg to get out of the trap you're in :)
