What does it mean when PPS goes down but SPS increases between two different archiectures? #2

These acronyms come from line 572 in main.cpp. Curious what this means conceptually.

SPS = Sieves per Second, This means how many times it does the entire loop
and finds primes.
PPS = Primes per Second, This is how many Prime Numbers it finds per second.

So when PPS goes down, and SPS goes up, it means it is looping more sieves,
but finding less primes.

Typically more primes is better than more sieves.

Good luck,
Aero

In what practical situations would this happen?

Wanted to follow up. What would make this happen in real life? Have you ever seen this happen yourself?

When the prime numbers get larger, there will be less primes... so SPS will
rise, while PPS will drop.

This happens based on the Factorial(s) you may choose, along with the
Length of the Prime Numbers.

I have given up on this project, there are other miners that are much
quicker, along with the GPU miners.

Good luck on your quest.
