I rewrote a 3d game I created during my studies with D 2.0 to
manual memory mangement. If I'm not studying I'm working in the
3d Engine 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.

Did you try GC.disable/enable?
