Ok I'll check next time I mine. The blue part is the part that is reporting me such awful numbers (16-23 % stales). Efficiency was 87% (plus/minus a number I don't recall)
The blue and the red parts are showing the same information in different ways:
Total submitted shares: 180 valid + 8 orphan + 5 dead = 193.
Stale % = (8 orphan + 5 dead) / 193 total = 0.067 = 6.7%
But it is the red part that tells you what kind of problem you have (orphan vs dead).
Of course, these numbers are only useful after p2pool has been running for a few days. They start out at zero everytime you restart p2pool and for the first day or two, randomness will make it hard to know what the real pattern is.
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.
