Anyone know why I'm only getting a share once every 3-5 mins on
http://doge.netcodepool.org/? I only get around 125kH/s but earlier today I was getting anywhere from 1 to 5 shares a minute.
The variable difficulty on these kinds of pools seems to be a bit crazy. My diff sometimes jumps from ~128 to 1000 even on a single 7970 and it takes over a minute to get a share in.
Does somebody know if too high pool difficulty can affect income?
