Play 2 is probably slower than Play 1 in development mode at present. This may change in the future, but you only need it to be fast enough to reload the page

Play 2 is probably slower than Play 1 in development mode at present. This may change in the future, but you only need it to be fast enough to reload the page without waiting, so there's no reason to run ab against it. If you run it in production mode, then I believe Play 2 is astoundingly fast.
