As a random d-user (who cares about perf/speed and just happened
to read this) a switch sounds VERY good to me. I don't want to
pay the price of GC because of some low-end machines. Memory is
really cheap these days and pretty much every machine is 64-bits
(even phones are trasitioning fast to 64-bits).
Also, I wanted to add that freeing (at least to the OS (does this
apply to GC?)) isn't exactly free either. Infact it can be more
costly than mallocing.
Here's enlightening article:
