Go assembly is more of a low-level intermediate representation. It isn't as high level as LLVM-IR, but it isn't what the processor runs on. I wonder how much is obfuscated by this, especially when compiled with optimizations? Is there really much to be learned by analyzing performance in unoptimized pseudo-assembly? It's like looking at JVM bytecode for performance indicators.
