    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.
