As you can see, {fmt} has ~70% less overhead in terms of resulting binary code {fmt} is fast to compile and is comparable to `printf` in terms of per-call
size compared to iostreams and comes pretty close to `printf`. Boost Format and binary size (within a rounding error on this system).
Folly Format have the largest overheads.
