It's not so clear to me. A lot of the speed issues have to do with inefficient libraries that could be much better optimized and benchmarks that rely on those libraries. Another major issue is garbage collection which can be worked around.
I think it may be the case that Go is quite fast if you become an expert in writing fast go code - but that remains to be proved.
There is an example of a benchmark that showed Go being really slow but some simple analysis showed that the code was poorly written - or at least that it was not written well. The code was fixed up appropriate and a fair comparison was made (where both C and Go were doing the same thing) and it was very close to C in performance. And it turned out that the Java implementation already had those enhancements and would have been obscenely slow too. So one has to be extremely skeptical of any benchmark.
I'm not defending Go, it may indeed still be very slow but I'm reserving judgement for now. C code is usually fast because we know how to write C code and we are often forced to do things manually that some languages do automatically at a cost - but we don't have to use those language features.
One issue for me is "what is the point" if I have to go too far out of my way to write "pedal to the metal" fast code. I guess the point is that if you find a good language you can use it for more things. The idea of being able to use Go for high performance things as well as quick scripts without the pain of C is appealing - even if I still have to work harder to write "seriously fast" code. Is Go than language? I don't know.
