Java is compiled to bytecode, for later compilation to machine code at runtime (JIT). Go is compiled AOT, straight to machine code. It makes no sense to compare them. Unless you meant that Java's AOT compilation is faster than Go's?

The parent comment explicitly mentioned that Java is slow at compilation, which is just false. Also, there are single-pass compilers that produce machine code, they are not fundamentally slower than a byte code generator. Of course extensive optimizations will be more expensive.
