If you have requirements for high performance then the traditional C++ "ownership model" (I would say a better description is "ownership strategy") is definitely "slow". It's pretty "safe" in that you usually aren't going to leak a bunch with it but bull allocations, arenas, and freelists are all potentially faster. And you wouldn't use them if they were slower since they're (usually) more to deal with.

But even in software using these strategies, they probably will be using different ownership strategies in different parts of the code. Once you're writing high performance code, you will use specific strategies that give you the best results. But it's completey domain specific.
