I don't think that everything works fine, my actual stale rate is 1,4%. A week ago, I even had a stale rate of nearly 3%! I guess you still have to work on improving the stale rate

cheers iro
That is actually far greater than our median stale rate. We'd love to know a little bit more about your particular setup, including your hash rate, geo-locality, and what miner you use.
We'd love to work with you to isolate the particular cause of your high stale rate.
