There's really no reason for D to by any slower than others. It's 
just about the whole library package and how efficiently it's 

Eventcore is probably closest to the system and all above just 
adds more overhead.

I've tried to run .Net core out of docker (I'm using podman 
actually) and it seems to be more performant than .Net Core 5. 
But it was out of the container so maybe it's just that.

I've added switches to CLI to set some load generator parameters 
so we can test scaling easier.

Thanks to Adam I've also pushed tests for arsd:cgi package. It's 
in it's own category as others are using async I/O loops. But 
everything has it's pros and cons.
