Balthazar, mining at 1260kh/s with two 7970s I frequently get a difficulty above 500. Isn't it a bit too much? I personally would like better something around 200 (300 at most) as for now. Or a value a bit quicker (I feel like it's very quick to climb up, but very slow to fall down).
Let me explain myself: of course even a difficulty of 2000 wouldn't be a real issue - and, some months ago, I used to BTCmine at 999-difficulty with a mining power of just about 1350Mh/s, so... go figure

))
I'm just curious about it: do you
need to force so high difficulties to keep the traffic low? As the pool is growing, will they grow as well?
Thanks.
