For numbers near 2**32, factoring a prime number seems to take 150 times longer
I'm not sure that I understand this? Factoring a prime how?
(I should also admit that I don't know what a "n-order wheel" is, or why it would benefit me to use one :)
Also, as I'm limiting my inputs to 0 .. 2**32, I only need the primes upto 65537 in order to factor that range of inputs. Right now, I am trading a little space (130k) to gain speed by building an array of the first 6534 primes at compile time.

The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
