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

Yup, this has been my experience for a while now too. I don't know what changed
in the LLVM backend (or LDC's exploitation of its features) but LDC is clearly
ahead in its ability to optimize D code.
That said, the main place where DMD lags AFAICS is number-crunching. Other
stuff, probably not so much; and at least in my own benchmarks of various bits
of code, there are occasional surprises where some particular case seems to run
faster when compiled with DMD.
