You had previously provided me with an OS X version of this (
xyyxsieve.7z). As I am currently entering a phase where I will be sieving millions of large numbers, a 30% boost looks pretty good right now. I had started a sieve to 5e9 on
interval #21 back on August 12 and it is currently at 8% with an ETC of mid-January. Ouch!
