How much | speedup do you observe from it? It would be good to compare various | GCC optimization levels as well as the two versions of the code. well, the fact is i don't know how to measure this speedup? Could you suggest some agreeable method? You can run some computation-bound Lisp program in both versions of Emacs and see how long it takes. Just call (current-time) before and after. If the run time is too short to measure accurately, run the program 100 times.
