I've just found a kind of "benchmark" here that might be interesting to someone in forum.
The text is in Russian, but diagram is fortunately in English. Let me translate the summarize for you:
Получилось, что Go слил Node, а Node слила D но все вышли за пределы C10K.
It's such that Go lost to Node, Node lost to D, but all got above C10K.
And he didn't make it to build the only available Rust server yet.
