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.
