Quick Noob question: With the new cpu miner is it better to have high Sieve and PTest
for example; Sieve 756000 PTest 815000 or low like below?
Sieve 400000 PTest 425000

Got 2 old computers i'm using and have done research of the miners stats and best settings
But I was unsure on which is better high or low?

Thank you in advance
