It's an i3-4130. At n = 50,000 it takes 2.5 seconds per test, at 100,000 it is near 10.
As I swapped computers halfway and stopped in summer I can't really tell how many months it took to go from 25k to 50k.

Wow, I'm way off! Whoops. So it's more like 2-3 months on all of a quad core, or perhaps a year on a single desktop core. {whistles} That's quite a bit of work!

I'm now even more impressed we've made it over 20G on this effort.

That estimate makes more sense. If anyone can refine it, please let us know.

Please email primes to me, so I can continue the sieve for 300-500k.
