First off, let me admit that I am no expert on Garbage Collector Technology or Language implementation. I made this thread only to know if there is any attempt being done to improve the current GC's efficiency.

    As the Garbage Collection techniques are becoming more efficient, how is D keeping up with the competition?

    As far as I understand, our GC is not the smartest one out there which can be a serious bottleneck to the overall performance. D doesn't have an incremental GC (let alone a generational one afaik), and the (fully conservative, stop-the-world) one it has just isn't very "good". So D sometimes would force me to revert to manual memory management, which I have no interest in whatsoever.

    If you look at Nim, it has a nice thread local GC, it's claimed to be faster in theory. (I have a feeling it will pose problems if you want to go multi-threaded).
