My ping does seem pretty awful. Ehh, i'll just upgrade. Even if it doesn't help my mining, at least I won't lag anymore in dota2 and get ganked by riki.
You can still mine "ordinary" not so low diff coins even with bit laggy connection. I am OK with mining on middlecoin (even while running live TeamViewer session) on connection with 200+ms ping, but the same time middlecoin switch to some low diff coin with fast share submission, whole connection lags badly, mostly resulting in remote reboot.
