Without actually trying it, Math::Big::Factors says:

For very small numbers the computation of the wheel of order 7 may actually take longer than the factorization, but anything that has more than 10 digits will usually benefit from order 7.

As I'm limiting myself to 2**32, it probably won't help?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
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.
