Anyway, even this pure Python version can deliver pseudo random numbers at
some 200,000 per second, while the built-in generator does 450,000 per
second, so it's not bad going.
The built-in generator is using a completely different algorithm
though, so rate of generation isn't the entire story. How long is the
period of the one you're using? (How long before it loops?)
I believe it's 5*2**1320480*(2**64-1) according to the author's comment.
I haven't tested that.
(By looping I understand that to mean, before the same sequence starts
again. Because as the numbers are 64 bits, individual numbers will
inevitably be repeated from time to time.)
