Just because a language is compiled doesn't mean it will approach C++ speeds. The GC itself is a hard limit on perf. What I've seen in practice: 1x time: C

Just because a language is compiled doesn't mean it will approach C++ speeds. The GC itself is a hard limit on perf. What I've seen in practice: 1x time: C 1.5x time: C++ (with smart pointers) ~2x time: Objective-C (almost everything is a heap smart pointer) 3x time: Java, Golang (optimized GC languages)
