I'm not clear on how to run multiple miners.  When I run more than one instance of phoenix pointed at the provided address, my hash rate drops.  Currently trying to run three, soon to be four.

Edit:  Actually, it appears that I got the expected hash rate after starting my first instance.  But then when I restarted all three instances, the hash rate had dropped.  Going back to just the one instance results in the same lowered hash rate (about half of expected), so it's possible that the correlation with the extra instances was just a coincidence.  When I point my instances back at arsbitcoin pool, the hash rate returns to the expected rate.

Disregard. I was making a stupid.
