Try 50btc.com (or btcguild or abcpool). 
I've given up on p2pool.  There is something seriously wrong with it (or I just got a really bad luck.  Variance is a bitch, I guess)

In 12 hours on p2pool, my 3.5Gh/s rig generated (to be paid when block is found) a whole 0.31 BTC.  Yesterday I switched to 50btc.com, the earnings were 1.15 BTC in the same 12 hour period.

I like the idea of p2pool, however I'm not going to run my rig on p2pool just because I like the idea behind it. 
I'm not a religious person.  So I wish you all p2pool devotees good luck with it.

If someone knows how to make more money on p2pool than 1.5% pps, please post your p2pool/miner configuration.  I'd be willing to validate your results.

I assume you ran it for more than 12 hours.  I ran it for a few weeks, and reached the same conclusion as you. 

I'm happily mining on ozcoin.net now.  Free (donation requested) unless you want PPS.  And we're over 1.1 terahash/s for the last 24 hours now.  Yesterday was nice!!   Smiley  In the last 24 hours I got 3.57 btc after 1% donation with 5 gh/s.

Supposedly ozcoin averages about 750gh/s and a lot of GPUMax users have ozcoin as the backup pool.

I mine at Kano's Pool because it pays the best and is completely transparent!  Come join me!

He says "12 hours" multiple times, so your assumption is wrong...

Long term, p2pool is only paying 90% of what is expected.  I don't know why this hasn't sunk in... Some people are saying p2pool pays more than PPS and they are wrong as clearly demonstrated by the luck chart.  Other people are saying that p2pool pays far less than PPS and they are also wrong as also clearly demonstrated by the luck chart.

Comparing a PPLNS pool to a PPS pool over a short period demonstrates a lack of understanding of the payout methods.

Where is some formula how luck chart is created?
I`m not sure that "Hashing performed vs blocks produced" is accurate.
Maybe is is very wrong because of jumpers? They add much power for short period of time and killing match?
It looks like we NEVER make less calculations than we need!

I think that graph would better be called "Hashing performed based on shares found vs blocks produced" but why would this be inaccurate?

Hopping will not affect luck.  If p2pool's hash rate increases because of a new miner (hopper or not), then the estimated time to find a block will go down.  If they leave, it goes back up.

I have explained it in great detail at least twice in this thread.  Please search for the the answer.

I don't believe the luck calculations are wrong, and no one who has looked at it has found any errors. I have also compared the calculated luck to my actual earnings and they are consistent.  I believe we really have found only 90% of the blocks that a "perfectly neutral luck" pool would have over the past several months. 

I don't know if it is just bad luck or if there is something else going on (someone withholding block solutions, etc), but I don't think it is an error in how luck is being calculated or displayed.

Red line is what we do, blue blocks is what we need. Line is always over blocks = we always do more than we need to find block.
Or I not understand it correctly?
I wish to get some chart that shows:
- difficulty of block
- shares sent to pool
- difficulty of counted shares
- time of finding block
It should give some insight and check that chart is properly. I just can`t believe that all pools are about 100% (and more!) and we are abut 90% all the time...
It is possible to collect that data somehow? For last moth or so?

Are all shares being treated as the same difficulty?  I'm pretty sure some of the bigger miners had voluntarily raised their difficulty. Would that change the calculation?

It shouldn't matter as when you ask for a higher difficulty it counts as a multiple of regular shares. I asked for 1500 difficulty shares which would give me credit for 3-4 shares when i Found "one" share.

P2Pool doesn't keep a share-chain history (as I also mentioned on the last page)
You would need to get that information out of the p2pool log (assuming it is available there) and make sure your log is 100% complete for the time range you are interested in.

The SANE_TARGET_RANGE is what limits the range of served shares.  The max/min is the same number (which equates to diff 1). You would need to edit this range to allow for higher difficulty shares.


Changing this (and only this) makes the p2pool node reject lower difficulty work submissions, but cgminer on the other side still submits all diff=1 solutions found. Shouldn't the p2pool node be requesting higher diff shares, or is that being ignored by cgminer?

The last two blocks reported on p2pool.info as orphaned are not orphaned. P2Pool.info is wrong. I am showing 100 confirmations on 182892 and 20 confirmations on 182974.  Cool

Link to my found block list http://p2pmining.com/index.php?method=pool#ui-tabs-2

I noticed that too.  They show orphaned on p2pool.info but are shown as validated in blockchain.info

You are in a maze of twisty little passages, all alike.

Fixing it now.  I had a power failure and when the computers restarted, the wrong version of bitcoind started up which caused problems with the p2pool.info block detection code.

I no longer see the blocks as rejected. Smiley Did the luck chart get re-calculated?

The luck chart is calculated from raw data on your own browser every time you look at it.  Also, luck calculations are not affected by orphaned blocks (orphaned blocks still count as found blocks from a pure probability perspective and so are counted the same as a non-orphaned block), so it doesn't matter in this case.

Decided to just stop checking p2pool over the weekend as I got tired of seeing how few blocks were solved. Came back to see someone just ramped up to 19 GH/s to take the lead on p2pool.info...

"I don't know who you are. I don't know what you want. If you are looking for ransom, I can tell you I don't have money. But what I do have are a very particular set of skills; skills I have acquired over a very short mining career. If you give me back the spot of top hasher I won't care. I won't buy more FPGAs and GPUs. But if you don't, I will feel threatened, I will buy more FPGAs and my wallet will hurt even more than it does. Don't make me do terrible things to my wallet."
