Getting almost double rejects in the last couple of hours, and diff is too high, what is the need to do that? the pool was running great
the need was the server was not designed to get 100+ shares/minute from most miners, with hundreds of miners. Increasng diff reduces number of shares, and therefore reduces stress on the server. and with PPLNS in place, it doesnt really impact the overall functionality of the pool
i'm behind you man i'd rather the diff go up cause it's better than the server going down. That's the kind of thing that happens when the pool triples in hash within the last 12 hours
