More from the blog post:
It’s a common but false belief that reference counting (using shared pointers in particular) is better than garbage collection. There is actual research showing that the two approaches are just two sides of the same coin. You should realize that deleting a shared pointer may lead to an arbitrary long pause in program execution, with similar performance characteristics as a garbage sweep.<
That's an interesting paper, the symmetry between the two forms of garbage collection is a something to remember, but it doesn't contain benchmarks, you can't draw performance conclusions from that paper.
