twmz,

there is one thing in my setup which is not "standard" and this is the fact that my miner runs from an usb key so I have the miner at home and p2pool and bitcoind at work, so there is some more latency, I suspect.

I don't have my numbers at hand, but I have a lot less shares (I have less MHs) and a lot more orphans and dead shares.

spiccioli.
