Sexy-prime benchmark on Topaz vs. PyPy

Also inspired by https://gist.github.com/havenwood/4724778. Sexy-prime ruby script can be found there.

Code @ Python

import time;

def is_prime(n):
    return all(n%i!=0 for i in range(2,n));

def sexy_primes(n):
    return filter(lambda x: all(is_prime(y) for y in x),[(i-6,i) for i in range(9,n)]);

a = time.time();
sexy_primes(100000);
b = time.time();

print(b - a);

Result

Note: Following time is result on rubbish machine, so result may varies.

• Topaz (trunk): 19.18 sec
• PyPy (1.9): 24.44 sec
• Python (2.7.3): 308.45 sec
• MRI-Ruby (1.9.3-p327): 309.95 sec
