Aha, jeszcze jedno. Zaadaptowałem lekko Twój benchmark (morderstwo na stosie) dodając psyco (oczywiście tylko przy cpythonie). Wynik w tym wypadku: $ python fibo_zabiello.py 0.51163816452 0.495419979095 0.494167089462 0.494843006134 0.492959022522 0.494037866592 0.511044025421 0.495035886765 0.495697975159 0.495857954025 $ jython -J-server fibo_zabiello.py 8.29499983788 7.11400008202 7.17999982834 7.15900015831 7.18099999428 7.09899997711 7.16899991035 7.18099999428 7.14699983597 7.09300017357 Jak widać hotspoty hotspotami, psyco ma przy obliczeniach większy potencjał. PS Kod: from timeit import time try: import psyco psyco.full() except ImportError: pass def fib(n): if n <= 1: return n return fib(n - 1) + fib(n - 2) for i in range(10): t = time.time() fib(35) print(time.time()-t)
