Mine is settling around 105 coll/min with Ubuntu 12.04 after warmup period. It doesn't mean much though because none of my shares are being accepted.  

Every so often it says 'connection to server lost - reconnect in 45 seconds'. Then, it connects again and the shares are actually accepted for a while. Eventually, the shares stop getting accepted and the whole process repeats. Anyone else seeing similar behavior?

I'm going to let it run overnight and see how it goes.
