We must also be clear what the requirements are.

Suppose you are GotRocks Inc and can have lots of processors and lots of 
storage but you must finish 90% of transactions in 1 second and the rest in 
10 seconds. Suppose you are looking at a back end database server.

Now the costs of reference counting can be beaten by having more 
processors. But the costs of collection are a huge lump right where it 
hurts. Collection can only be subdivided so far because of cross pointers.
