There are many benchmarks showing Java faster than Go. The trick is picking one that people agree is representative.

It shouldn't be surprising though. "Peak performance" doesn't include start-up time, and ignores memory. If you discount both those, there's no reason that JITted native code wouldn't be faster than a runtime that includes goroutine scheduling.

unless goroutines aren't in use, which means the generated code probably matches what llvm and C would generate.
