Quart Vs Flask (programming.dev)

submitted 1 month ago by [email protected] to c/[email protected]

Hi,

I've read quite few articles about Flask Vs quart.

But the one that I found do not go deep.. :/ (and are big adept of copy/past ...)

So, beside the extra features (ASGI, HTTP/2, WebSockets..)

I'm wondering if async/await in this context give a real boost of performance ?

When a client connect to a worker I don't think that while await, will allow another client to use the same work ? or am I wrong ?

Do you have any metric ? Or if you switched from Flask to Quart di you noticed a gain ? lost ?

Thanks.

A few months ago I evaluated Quart to see if it would be a better option for https://piefed.social. It was easy to port my code from Flask to Quart and everything was mostly working within an hour or two. In the end I decided not to proceed with Quart because the performance gains only happen when there are many concurrent users and that time might never come. However the extra complexity and potential for problems was there immediately, so I just stayed with trusty old Flask. It's good to know that switching to Quart is straightforward if I need it in the future.
