I am not aware of any way to profile the innards of a byte-code compiled function (which doesn't mean that there ins't a wayâ?¦) But if you compile to C (not byte code), technically yo could use a profiler for C to get some information about what needs to be sped up. I expect it'll take some work to figure out how to profile such a function effectively, as the code is generated and loaded into the kernel by default. You could split the function off and call it from a separate program (not the kernel) to profile it more easily. I have never done this personally.
