I think you missed a '0' there. And not all applications are created equal, some really do have more business logic and systems requirements than others. 100K visitors on one machine is usually doable, 200K as well if the website isn't all that complex and the interactions between users aren't all that complex. Above that you're (usually, not always) going to see some clustering.
If it is just static content then you should be able to saturate your uplink from one single machine.
The 10K number applied to the whole setup, and that's now comfortably served from one box (as it should be). It could probably handle 10 times that number now without too much in terms of additional tuning (if any), above that it might require more work.
