Not bad at all. How about using http://www.sagemath.org/ (written in Python). sage: time primes_first_n(10^7); CPU times: user 4.36 s, sys: 2.43 s, total: 6.79 s Wall time: 6.88 s That used 3G of RAM, you could certainly go higher if you have more memory. ----aht -- http://mail.python.org/mailman/listinfo/python-list
