This question makes a lot of assumptions that aren't necessarily true or applicable.
For high performance computation or throughput so called web development isn't an option. Then you need to do what the corporate giants from time to time have done, write parts of your web app in C++ or similar language.
If you can afford overhead or can't afford such programmers, then web scripting is probably what remains an alternative.
If you can put it in performant binaries and write such code fast, then you probably should unless you expect hardware changes breaking it further down the line.
