	It also depends on what you call "10,000 users".

	Like Joshua said, if you're talking about 10k simultaneous users, thats 
basically impossible to serve with only one server.

	Some of our fastest apache machines (serving only static content) are 
usually able to deliver around 6,500 hits/sec at most. And we're talking 
about quad Xeon machines, with 8 Gb of ram.

	In counterpart, each of those machines serve at least a hundred million 
(static) requests per day, and usually much more then 5 million distinct 
users per day.

	As you can see, it all depends on your exact needs.
