I've been mining in p2pool the last 3-4 days and I'm wondering, if anyone else has these thoughts, that maybe something is not operating as efficiently as possible.  I am looking at p2pool.info and if you look at the long list of blocks, each time miners get out of a good block, and get some % of what was expected, it goes immediately into a new block but it ends up like the one 3 days ago, at -352% expected.  Is this because of the issues around p2pool running on a computer?  Is this just part of the system or can we tweak the efficiency and if so how?  I know probably all p2pool miners are configuring/tweaking the best they can, I'm just curious why there seems to be so much mining work inefficiency.  I'm using Ubuntu and p2pool runs great.  I get a lot of "peer sent entire transaction "jerlkjerlkje" that was already received.  My stale rate right now is 17.2%, that is somewhat high isn't it, given I have an Intel Core i3-4130 CPU @ 3.40GHz x 4, and I don't use the computer for anything but p2pool and btc wallet.  I guess it's the latency issue, is that the real problem causing the inefficiency in numbers?  OR do you guys think it will balance out later?  Just curious.  I really love p2pool by the way, I think it's definitely the way to go for miners.
