Remember that Go vs D MQTT thing and how we wondered about dmd vs gdc?

Have you done any profiling of your code to really get a feel on 
what's taking the time? If it really is io bound then there's 
nothing gdc can really do to make it better.

Having said that, I've been getting similar results from gdc and 
dmd recently too, with ldc coming out as a very clear winner.
