Also, I am running cgminer 3.1.1 (on windows 7), which doesn't seem to have the disconnect, crash, and non-restart issues people are reporting with newer versions of cgminer. It's stable for at least a week on either server with all my rigs.
i will say using load balance now i dont see my gpus goin idle even tho im still getting getwork failures i did complile a few differt versions of cgminer with the changes h20 gave us.
I was under the impression you can not do load balancing when the two loads are different currencies, with different diff. Are you sure its not just only mining DOGE on eu now?
if you mine just on the us server and monitor you gpu usage you will see the usage drop then pick back up but when using load balance the gpu stays solid.
