Yeah I noticed it appears to only be a problem with deepbit as well when the long poll shows up in the console. I added a post in the deepbit thread for newbies but no response yet.

Hi, I noticed that the problem I was having with GUIMiner only happens when using deepbit. This happens when long poll shows up in the console log. Please see the thread at:

Any ideas? I would like to try deepbit if possible.

I have been watching the logs and the drop occurs on a new block. I see this in the log:

013-02-19 22:27:12: Listener for "Default": pit.deepbit.net:8332 19/02/2013 22:27:12, long poll: new block 00000374xxxxxxx

Hi all,

I am new to bitcoin mining and when I start mining it goes at 280-300 Mhash/s and then seemingly randomly drops down to 200-300 khash/s. It will stay there until I click stop mining and then start mining again. Immediately after clicking Start mining again it resumes back at 280-300 Mhash/s.

Is there a setting somewhere I need to modify somewhere?
