According to micro benchmarks C is about twice as fast as Go. https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/go-gcc.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... That is already pretty fast, and I guess the difference in practical scenarios would be even smaller since external systems like DB's won't change their speed if you call them with another programming language and because production code is not always as optimized as benchmark code.
