deparement of Havok. As I needed to pratice manual memory
management and
did want to get rid of the GC in D for quite some time, I did
go through
all this effort to create a GC free version of my game.
The results are:
DMD GC Version: 71 FPS, 14.0 ms frametime
GDC GC Version: 128.6 FPS, 7.72 ms frametime
DMD MMM Version: 142.8 FPS, 7.02 ms frametime
GC collection times:
DMD GC Version: 8.9 ms
GDC GC Version: 4.1 ms
As you see the manual managed version is twice as fast as the
garbage
collected one. Even the highly optimized version created with
GDC is
still slower the the manual memory management.

Feedback is welcome.

BTW, your blog post appears to have comparison misspelled.
Also "development".
It was interesting to read it. What about GDC MMM?
