It's not actually the fastest. Check out the tabs at the top of the benchmark. You are only looking at basic JSON serialization on an i7. A more realistic benchmark is the 'fortune cookie' benchmarks which actually hit a database and does some modifications on the results - which most of your requests will do. Go performs at only 50% of the more optimized Java/C++ frameworks in this case.
