Just realised, although I said it in a PM to Petrus, I hadn't said it here, but I'm in with my old Quad .
Atm it's just crunching on 2 cores whilst it burns off the remaining Asteroid WUs, actually that could take a while as it had a 4 day cache of them, for 4 cores!
Wondering if I'd be better off going all on A@H & then switching when the WUs are depleted, don't suppose it'd make much difference though.....
Client's showing ~4k ppd with the 2 cores.
FAH uses Quick Return Bonus (QRB) on most work, meaning running 4 cores for 24 hours will likely give significantly more than running 2 cores for 48 hours.
Using two of my own results as basis, and just assuming linear decrease due to #cores (not really the case for HT) together with the bonus-calculator located
http://www.linuxforge.net/bonuscalc2.php
Project-9004:
1 core: 519 PPD -> 4151 PPD if could multiply by 8 to use 8-core
2 cores: 1468 PPD -> 5870 PPD if could multiply by 4 to use 8-core ==> 41 % higher than 1-core
4 cores: 4137 PPD -> 8273 PPD if could multiply by 2 to use 8-core ==> 99 % higher than 1-core.
8 cores: 11700 PPD ==> 182 % higher than 1-core.
Project-8571:
1 core: 501 PPD -> 4011
2 cores:1418 PPD -> 5671 ==> 41 %
4 cores: 4012 PPD -> 8023 ==> 100 %
8 cores: 11336 PPD ==> 183 %
So, based on this, running 4 cores for 24 hours would get 41 % more points than running 2 cores for 48 hours.
