0 blocks about 72 hours on 11 G Sandy dual core cpu`s; 2x i5 and 2 i7, i test every release.
something's severely broken in your setup - 20 systems here. Seeing avg 1 block/hr.
Which build are you using?
Sunny's build. Tbh, I'm not sure I trust the "chasing pps". It was mentioned before this isn't a greatly indicator of how quickly you'll find the blocks.
