If you think that my entry in p2pool is breaking up things, I can move my miners to solo-mining. I'm talking of around 250GH/s.
I joined having in mind to help p2pool to perform better, not to upset people.
Have you adjusted the difficulty to compensate for your high horsepower?

you can set manual difficulty with p2pool?
You can adjust difficulty by making the miner's user name <username>+<difficulty> for example: username+1
This would be useful to decrease the load on your p2pool node on big time hashrate miners.
You would not want to increase share difficulty above p2pool share chain difficulty or a miner may discard work that could have been added to the p2pool share chain.
This has been disabled in recent versions because forrestv thought the shares that where not difficulty 1 would screw up some mining programs.
To allow this to work, you need to edit the p2pool/bitcoin/networks.py file. On line 26 change:
SANE_TARGET_RANGE=(2**256//2**32 - 1, 2**256//2**32 - 1),
To:
SANE_TARGET_RANGE=(2**256//2**64 - 1, 2**256//2**32 - 1),
The other option (/) doesn't seem to be currently implemented anywhere (I PMd forrestv to find out about this)
CGMiner doesn't seem to be affected by different share difficulties from the tests I have done. That is all I can vouch for.
