Hi,

I've been reading this thread looking for some indication of performance but haven't come across nothing useful. I currently own a few machines and have been testing an AMD Athlon 64 X2 @ 2.6GHz, which gets me 0.012 chains/day.
From what I've read some people seem to be able to get much more than that, though I'm unsure if that number is related or not to the current difficulty.

Am I missing something or is current performance on this order of magnitude? I'm using this miner with default parameters, compiled myself.

Guidance is greatly appreciated. Thanks.

Your chains/day is fine. And yes, it is related to the difficulty because now we're looking for chains of 10 prime numbers, whereas previously it was 9.

Specifically, chainsperday refers only to the integer (whole number) part of the current difficulty value. It does not reflect the current fractional ('decimal') part of the difficulty value.

You can casually say that, you could take the chainsperday value that you are shown, and multiply it by the fractional difficulty part to get rough estimate of how many blocks you might find per day, assuming no variance. But as diff gets higher and higher, the "no variance" thing becomes more and more meaningless as you stare at your computer for weeks wondering why you haven't found a block yet. (The human brain is terrible at statistically interpreting infrequently occurring events over long time scales without bias). The precise calculations are a few pages back, have a look at mikaelh's recent posts.
