Complete blocks are never sent over the P2Pool network; the most you should ever have to burst upload when you get a share is ~2kB to every peer. If decreasing the block size helps your stale rate, it's more likely a latency issue within the P2Pool codebase that can be fixed, instead of a result of your internet connection.

zvs, what kind of hardware were you running P2Pool on when you got this?
Local rate: 7.74GH/s (7.2% DOA) Expected time to share: 0.0917 hours
Shares: 31 total (28 orphaned, 3 dead) Efficiency: 0.000%
Payout if a block were found NOW: 0.49253475 BTC to 1Zevusze7BjTpp4srJhx4zkRBxpbgwU4A. Expected after mining for 24 hours: 0.664 BTC
Current block value: 26.55448192 BTC Expected time to block: 11.5 hours

that's fancy
i'm guessing it's because the size of my blocks are too large?  it looks like it's running 900KB atm.
ok, back to 0, heh...
Having every single share orphaned is a sign of bitcoind being broken or some other misconfiguration, not any fixable latency. Did reducing maxblocksize to 0 help?

BTW, Stratum support is finished and will be released later today.

When whould this Version been published?

Maybe not, but at least if you had >50GH devices it wouldn't struggle with keeping it busy.

After two hours on p2pool/cgminer/Stratum, I got a block http://blockchain.info/block-index/329787 and Best Share reads 9.69M

Current difficulty is 2.98M. Shouldn't I get credit for at least three blocks on that?  Grin

My incoming peer has always been 0. Any cause for concern?

That means you aren't forwarding the p2pool port from your firewall.  Probably okay.

I think mine increased as well, and I'm getting less shares.

P2Pool release 10.0 tag: 10.0 hash: 541fa38d384428337da22f5115ae8ce92ed3f8e2

This upgrade is critical for fixing an issue that causes us to lose blocks. Please upgrade!

Windows binary: http://u.forre.st/u/twrtsxtl/p2pool_win32_10.0.zip
Source zipball: https://github.com/forrestv/p2pool/zipball/10.0
Source tarball: https://github.com/forrestv/p2pool/tarball/10.0

Changes:
* Stratum support - just connect to stratum+tcp://127.0.0.1:9332 or let cgminer autodetect and switch using the X-Stratum header
* Fixed coinbase value bug that caused two produced blocks to be invalid - shares produced after a quick series of transactions are produced on the Bitcoin network don't include all transactions due to the share size limit, but the fee was calculated improperly in this case
* Increased default donation amount to 1%  to continue to support post-halving development

EDIT: You can disable cgminer's auto-switching to Stratum if you think Stratum is worse by using --fix-protocol on cgminer

I'm forcing LP.  I lost 1/3 of my shares overnight, not sure if it's because of the bug, or if stratum.  I'll try again once my payout gets back up to par.

I also keep lowering the maximum incoming connections.  I noticed I start getting stales left and right when the connections increase.  I dropped it to 10, then to 5, and now to 3.  Seems to be working well to keep the stales and deads at bay.

Or --disable-stratum in BFGMiner. But note that in general, stratum is better than getwork and makes good sense for local stuff like p2pool.

Makes sense, but reality doesn't always match theory.  As I said above, I have it disabled for now until my payout gets back up to par.  Whether it was stratum or a p2pool bug that caused it, I don't know.  I can tell you my local rejects from cgminer increased with stratum.

P2pool becomes incompatible with some miners. Even with Stratum mining-proxy itself!

Both BTCMiner (v121126, cluster mode) and BFGminer seem work well with p2pool Stratum for me,
I don't see the same error for BTCMiner, running on amd64 Linux,
do you use different version or platform?

BTCMiner does not have any Stratum support, only GetWork+ var diff. How it can be working for you, mate?  Cheesy

Haha..I just mean the version of p2pool with Stratum support Smiley
But maybe I don't run BTCMiner long enough to see the error.
