Thanks. Asynchronocity is one thing but there is one thing that in theory can achieve better performance than asynchronicity alone: I'm referring to the reactive programming paradigm which benefit from the concept of backpressure. If you've heard of it, do you think it could achieve even better performance? https://medium.com/@jayphelps/backpressure-explained-the-flo...

I had a look at the video, but I don't think there is backpresure in this benchmark since there is only 512 connections max and each connections wait for the server response before sending a new request. So in other words the load generator never send more request/s that the server is able to handle. (tell me if I missunderstood backpressure)

Mmh then I wonder if the techempowerUp benchmark suite would benefit from a new benchmarck that is backpressure sensitive, thus increasing its coverage of real world workloads?

yes, it has been discused already to increase the number of connections. But still, several thousands of simultaneous connections is still ok for the best performing frameworks...
