As far as I know, the processing power necessary to do the garbage collection, increases exponentially by the number of bits involved. This was heavily discussed here when the first 64-bit Intel processors arrived, and it's also one of the reasons why a 64-bit processor isn't that much faster than a 32-bit processor.

embolded part knew to me.

quick googling only turned up:

and while there certainly is a correlation between heap size and GC time, alloting 1/3 more for increased pointer size should not fall in the same category.
If you come across such articles, pls. give a hint.
