On average, Go code is about 50% as fast as C code in calculations and algorithms, usually, and has more lines of code for equivalent functionality without cheating. Do your benchmarks tell you something different ?
Java is about 10% slower than C. 30% or so if you "don't cheat" (meaning write a direct translation of C code into java, e.g. using char[] instead of string)
There's also that C encourages you to write faster code, at least it does for me. Java, Go, and every other language I know, encourage me to do string mangling by making lots of temporary strings. C doesn't really allow for that, instead making me think about doing in-place string editing, which is far, far faster than using copies. Of course, get the tiniest little detail wrong and it'll blow up, but there's no beating it in speed.
- _ph_ 10y agoYes, in my daily experience, Go is roughly on par with C code. There are a few constructs that the Go compiler does not optimize yet (jump tables), but other than that they are pretty close.
