Okay by just fixing my logic, I go up to 839.42 Req/Sec for 10 sec and 601.74 Req/Sec for 30sec which is pretty impressive!

My other question here is, can I specify directly in dub the compiler I want to use? Something like this :

dub -compiler=ldc|dmd ...

Because I really want to try to reach 1000rps

I've update my SQL dump with 100 entries and now and I have better results!
Pretty amazing :)

Why not to use distribute oprion?

it its a flawed strategy.
what you should do is let the kernel handle it and use SO_ REUSEPORT
libasync supports it.

see e.g. https://github.com/rejectedsoftware/vibe.d/issues/1139
and https://lwn.net/Articles/542629/
