I've just started to play around with D, and I'm hoping someone can clarify
this. I wrote a very simple program that just allocates lots of objects, in
order to benchmark the garbage collector in D. For comparison, I wrote the
programs in C++, Java and D:
C++: http://gist.github.com/122708
Java: http://gist.github.com/122709
D: http://gist.github.com/121790
With an iteration count of 99999999, I get the following numbers:
JAVA:
0:01.60 elapsed, 1.25 user, 0.28 system
C++:
0:04.99 elapsed, 4.97 user, 0.00 system
D:
0:25.28 elapsed, 25.22 user, 0.00 system
As you can see, D is abysmally slow compared to C++ and Java. This is using the
GNU gdc compiler. I'm hoping the community can give me some insight on what is
going on.
Thanks,

Can someone try dmd and ldc as gdc is dying (if not already dead). Also
code in the iterations and take out the command line reading and
printing so to make it accurate.
