Running on win7 python 2.7 32 bit it uses around 30 seconds avg.
Running on xubuntu, 32 bit, on vmware on windows 7: 20 seconds!
The code runs faster on vm, than the computer itself...
The python version in this case is 1.5 times faster...
I don't understand.
What causes this?
The random module uses os.urandom,
No, it doesn't. random.random() is an alias to the random() method on the
random.Random class, which uses the Mersenne Twister to generate values.
os.urandom() gets called in the initial default seeding, but not for each value.
