>It is well-known that the amortized cost of naive reference counting is considerably higher than that of a modern tracing garbage collector True, but I think these comparisons are often done under the assumption that memory utilisation remains fairly low. Tracing GCs react very badly to growing memory utilisation in my experience. This is of course ultimately an economic question and maybe it should be modelled that way.
