Gold standard for scalability? There are certainly others. Check out numbers for Haskell: http://snapframework.com/blog/2010/11/17/snap-0.3-benchmarks http://snapframework.com/blog/2010/11/17/snap-0.3-benchmarks http://www.yesodweb.com/blog/preliminary-warp-cross-language-benchmarks http://www.yesodweb.com/blog/preliminary-warp-cross-language... Would be interesting to repeat the author's experiment exactly, but in any case I would expect an order of magnitude upwards difference in performance. Haskell gives you non-blocking IO without the hassle of callbacks, multithreaded operation and more.
