That's wild that shared ptr is so inefficient. I thought everyone was moving towards those because they were universally better. No one mentions the performance hit.
Atomic instructions are quite slow and if they run a lot... Rust has two types of reference counted pointer for that reason. One that has atomic reference counting for multithreaded code and one non-atomic for single threaded. Reference counting is usually overkill in the first place and can be a sign that your code doesn't have proper ownership.
