What's some examples of the code changes that you made? And did you just do repeated disassemblies of the functions to see that it was using the correct instructions, or did you do some benchmarking to show your changes were actual improvements?

Gosh, I'd have to see if I can dig it up this was a few years ago.

I did all of the above, plus profiling (sb-sprof combined with disassemble will show assembly level profiling).
