Yes, generational GC for example. 

Back in the eighties and early nineties, when Symbolics introduced
generational GC on their Lisp Machines, large programs did run faster with
GC turned on than without GC when the "Ephemeral GC" (that was their name
for Generational GC, IIRC) was turned on because this reduced working sets.
