i asked before, but it was ignored, so ill ask again, when can u change the diff ? 512 is too big .. come on ...
When I write my own stratum server which will be more efficient and will most likely support vardiff. Too much is going on right now for me to have time for this. I hope to do it sometime in April.
512 isn't too big at all. If you don't want to hop pools mining an hour here and another hour somewhere else, then it shouldn't concern you. If you're here for days, then you'll get the same profitability as with any other diff. Lowering diff only lowers variance so it might affect profitability only in short term span because luck will be more important then.
But as an interim solution can you not also provide 128 or 256? I'd imagine it's simply a matter of re-enabling a switch. As I recall, you said the current diff of 512 is suppose to be temporary while you tracked down some issue back then -- that was over a month ago. Is there still some other problem that requires you to keep the diff setting as is?
