Increasing number of routers in FastAPI

[rozeappletree]

Hi,

I have a concern. How good of an idea is it to have separate router for each endpoint and how does it affect performance? For example, if I am going to build 100 endpoints with 100 different independent python functions, what is the best way to build architecture for HIGH PERFORMANCE.

Thanks

It's a good idea, and it only affects startup time.

The main performance hit should actually be in your code and not in how you structure the routers. If you want to squeeze performance, use async functions with async-compatible libraries, and do the output data conversion yourself (instead of having the default by FastAPI), and return an ORJSONResponse directly from your path operation functions.

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I'm checking each one in order.
