Perhaps I'm overly critical and/or cynical, but it's difficult to take this page seriously when there's a graph right at the top showing that IIS 7.0 Windows / C# can handle 0 concurrent users per sec.

Either this is a poor attempt at humor (indicating a naive or dangerous opionated author), or the testing isn't thorough (indicating the author isn't thorough enough to care despite making very bold claims about similar software). Neither lead to very promising conclusions about the quality of the software.

If you look closely, the point is a little past 0, perhaps 5-10.

I've read somewhere that, a laboratory has been able to to acheive this level. I'm unable to find the article to back this claim up, however.
