LaurV, thanks for the advice.

I read here and at PG that time per factor found increases only with sqrt(n), so I was explicitly told not to split the sieve. At the beginning I did just that because I thought it was the way to distribute sieving between several cores.

There is nothing like "i should have sieve it higher"
By that I meant having candidates up to n = 16 400 000 in the sieve, not larger p. It would have taken only twice as long - at least to my understanding.

Does you method take that into account? Sorry if this is a stupid question, but I'm really not sure. And various people said large sieving files are good (put simply).
