Go is pretty well optimized, for a garbage collected language, though of course it doesn't match up to a language without garbage collection. But much investment has been made in fast compile time and runtime simplicity, at the expense of some remaining potential performance gains. While Java is generally slow, that's more the fault of Java developers and their FooDangleProviderModuleBuilderBuilderFactories. Due to runtime optimization Java can be nearly as performant as non-GC languages. In principle there are even scenarios where it can exceed the performance of any ahead of time compiled language.
