What you are doing, if I understand you well, is a way of scaling 
the server to handle high amount of traffic.

If that's right, then I'm not sure how the number of PORT is the 
issue. Irrespective of the port, the server resources remains the 
same.

And if that's the case, then you might need a load balancer (or 
use nginx or any of the options I've used in my projects). In 
that case, you run multiple versions of the server in stateless 
environments... scaled up or down on demand.

Been a long while since I wrote some vibe.d tutorials though :)
