Not really. If you are performance conscious you structure your
data and algorithms to match the tools you are using. Therefore
performance oriented RC outperforms GC. You can have a lot more
special-casing with RC in a realistic implementation. Few
application authors consider rewriting the GC, but doing your own
minimal overhead specialized RC is quite common…
