Ask HN: Do you know any good web framework performance comparisons?

> ...trying to create a new website...

Guessing that massive web traffic will (at best) be kinda far in your future - how useful are metrics such as TPS here?

I'd pick based on the resources needed to set up & manage your ops side, developer productivity, time to market, and such. With a veto on that winner possible, if its performance is seriously bad.

Something I'd probably do is make a very basic app (e.g. 'todo' app) in each framework, deploy all 3 to heroku, and check out the 'metrics' tab. For a few hours' work, that should give a rough idea of CPU and memory, at least for a very small app.

One other thing:

This is a perfectly sensible objective, but always keep in mind any trade offs between development time and server costs. Sometimes less efficient frameworks are faster to develop in, and it can be worth suffering a slightly greater server bill to get an MVP out quickly, especially if the server bill is small to begin with.

Ruby is traditionally quite heavy compared to Python and PHP, similar to Java and ColdFusion, though that is likely less a problem these days. I personally have found Flask (Python) to be super lightweight and still has a great ecosystem of libraries and packages.

For the final word in web speed, though, G-WAN - write your code in C and feel the lightning ;)
