I believe you are not on new firmware? I strongly advise people wait till they have new firmware as the new cgminer code is optimised around it and vice versa.
Thanks! I'm back on 3.11 now and my recovery time is back to around 5 seconds.
Has the new Firmware been pushed out to anyone yet? (Apart from you?)
I'm not running on the RPI right now, so I won't get the Firmware update automatically.
