It's a bit offtopic but I'd be grateful if someone can explain why D
with structs completes this simple benchmark (see attachment) so slowly
compared to C++ with classes on stack:
D struct - 27.85s
C++ stack - 8.32s
D class - 271.58s
C++ heap - 249.32s
Compiled with "dmd -O". -release decreases performance by 10% in this
case. -inline doesn't affects it at all.
Well, you don't compare C++ vs D struct speed but rather C++ vs D IO.
I believe writefln is a bottleneck.
Nevermind, I didn't understand the benchmark from quick glance.
