My understanding is that there are some lock-free algorithms that we do not know how to write without garbage collection [Keir, 2004], so you strictly are giving things up, because you can't use those algorithms.

(But I'm not completely up to date on latest lock-free work.)

I optimize these days mostly by deleting lock-free apparatus.
