Maybe splitting the sha256 coins into two sections would help in this?
First section for the "dinosaurs" I mean "Large" Miners needing large steady difficulty.
The second section that could possibly respond quicker to difficulty changes and lower settings.
I would like to do a git clone of the repo on github but the challenge is I do not know what differences there are between that & what's on zpool, or if there are any at all. If there aren't and crackfoo can confirm, I'll get the code from github and see if I can find an answer to the issue.
it's the same as the yiimp repo.
