The previous port will now stay alive for 60 seconds before closing, this should allow sgminer to see the new port before it closes the old port, allowing the failover to happen much quicker.
Thanks!
I don't know if this has anything to do with this or not:
Buy just today I notice ~4 min +/- 30 sec to make the switch. I'm not sure where I was before, but I never noticed anything this long. I tried --failover-only (where I didn't have it set before) and no difference.
Could it have to do with : --expiry 1 --scan-time 1 --queue 0
For now i'm off of the algo switching ports and on 4440.
