Isn't there a decent chance the bottleneck is vibe.d's JSON 
implementation rather than the framework as such ?  We know from 
Atila's MQTT project that vibe.D can be significantly faster than 
Go, and we also know that its JSON implementation isn't that 
fast.  Replacing with FastJSON might be interesting.  Sadly I 
don't have time to do that myself.
