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).
