There's no settings to check. I mine on BFLs so there's nothing to change.
Using 1 instance of CGminer in load balance mode on EMC servers US2 & US2 and OZ US server ports 8332 & 80.
It's a direct comparison.
There are 3 things that affect the reject rate for a BFL:
1) If a pool doesn't accept stale shares then another pool that does accept stale shares will get a lower reject rate
Well that's pool dependent.
You'd need another pool that does accept stale shares, but doesn't charge anything, to be able to make more BTC on the other pool.
2) If you are submitting stale shares on one pool and not on another pool then the pool you are NOT submitting them to will be have a lower reject rate.
However, the pool that you ARE submitting stale shares to will have a higher payout, since on rare occasions those stale shares might be accepted
(the BFL code does not abort stale work before it completes)
3) Network performance.
If you have REALLY bad network performance with one pool and good network performance with another pool, then the reject rate will be higher on the pool that you have bad network performance on.
I'd be surprised if that was the case with all Ozcoin servers ...
... so which is it?
