For me, my source is my microbenchmarks, which are testing just loop
with computation, i.e compute intensive data parallel. There is plenty
of other stuff.

100,000+ lines of code is a total irrelevance regarding system
performance, as anyone who knows anything of profiling and benchmarking
will tell you.

If C is the only viable language why has Java got the majority of the
commercial market. C++ and Fortran have the vast majority of the
computational world.

Where is D is this arena. It is either C++ or C++ in the high
performance graphics arena. If there are no AAA titles written in D why
does this email list have anyone on it?

Clearly I think your response is just trolling, I will stop feeding the
troll.
