My processor is a 1 gHz Athlon Thunderbird (the ones with the 512k cache I think). I'll go ahead and temporarily kill the sb program after it's done with the current data set to speed up the sieve (should be about a ratio of 2x faster since currently they're both taking up about the same processor percentage).
EDIT: I haven't checked the "create new .dat file", but before I upgrade to 1.07 I'll make sure to copy all the factors into a text file and write down the sieve's p progress so that I don't waste any time.
