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, Diwaker
