Sorry, I'm not going to go through all the pages, but can someone tell me if this pool uses VARDIFF or if it's set at 512?
It's set at 512 to reduce server load. Unfortunately with the crazy growth experienced recently there are still some server overloads/disconnects - hence the need for EU Server
So after the EU server, would it be lowered? Setting it at 512 would cause less shares going through, wouldn't it?
I believe somewhere in the 100+ pages there is a discussion about that and the higher difficulty does not ultimately affect the pool profitability.
But it causes less shares to go through. For example: I get 3,000+ kh/s, and when I monitor it at say 128 diff, I'm constantly sending accepted shares, when it's 512, I'll see it accept a share, but sometimes it takes too long that we already move on to the next block, so my hashing power during that time gets voided.
I hope I'm making sense.
edit: FWIW, I normally get over 3,000kh/s, but on this pool the most I've seen is 2,500 (i'm assuming this is because of the difficulty being at 512)
