Quart Vs Flask

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.
