Benchmarks "Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

How do you suspect it performs in heavily threaded code? (you need mutexing both on the refcount and on your heap).

Faster than GC if it was to free memory at the same rate.

GC performs better than manual memory management only in a small subset of scenarios. It is true that it is good enough for many more, and that it keeps dumb programmers from freeing used objects and the like.

However, as soon as their design assumptions aren't met they fail badly. Generational GC aces object creation and destruction benchmarks. As true as it is that it bloats up until virtual memory dries up, when faced with real world apps that don't follow the general rule.
