How about compared to retain/release/autorelease?

?? I admit the last time I really coded in Obj-C was for NeXTSTEP. But back then init ultimately called malloc, and release ultimately called free. In any case, yes, a good GC can be faster as it takes advantage of cache effects.

I upvoted you, but I was mostly just quoting the jwz article from 1998.
