LLVM helps a lot here. We're generally in the same order of magnitude, sometimes faster, sometimes slower. It depends, as always with performance.
> comparible number of libraries
Yeah, this is a big one. If those C++ libraries also expose a C interface, we have zero-overhead FFI, but not all of them do. Crates.io currently has 1,893 packages, with a million and a half downloads served so far. It's a start, but always a weakness of a young language.

LLVM helps here too, though there will always be some embedded platforms and such that ship their own C or C++ compiler.
