You must be doing something wrong. There's a lot of overhead for frameworks like Symfony, yes. But it's possible to write reasonably productive and modern website code where you can get sub 20ms responses (doing auth, fetching from db, processing and rendering html). I know because I've done that, on PHP 5.4.
