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
