Then rounds, they should last 10 seconds, but they're often a lot faster, see:

I see that a few months ago rounds went from 5 to 10 seconds, so I'm asking wouldn't it be better to have 1 minute long rounds?

Share difficulty is set so that they will be found every 10 seconds on average.  Just as with bitcoin blocks (which are supposed to be found every 10 minutes but are often found 2-3 minutes apart or 25 minutes apart), there will be variance in how frequently the shares are actually found.

An average of 1 share per minute would be accomplished by making share difficulty 6x higher.  That would increase variance for any given miner (which seems to be the opposite of what you are looking for).

I've been mining on P2P with 760MHs for four days now, but I'm mining just one third, more or less, of what I was getting when I was on a PPS pool.

I do understand that there is variance, but now I need a day where I mine 8 times as much just to be on par with my previous PPS payout.


Given the pool's current/recent hashrate, our average time to find a block should have been about 10-11 hours.  So in the past 96 hours, we should have found 9 or 10 blocks.  In reality we have found 9 blocks in that time frame.

So, we are pretty much hitting the average.  You should have made almost exactly the same amount in the past 4 days as you would have on a PPS pool unless your share-finding-luck has been crazy bad.  If you really have seen only 1/3rd as much, something almost has to be wrong because you almost certainly haven't been that unlucky finding shares. 

Have you confirmed that your stale rate is not abnormally high relative to the pool? 

Are you getting approx the same hashrate as before as reported by p2pool?

Finally, I have moved all of my 500 MH/s to P2pool from deepbit. It feels good.

I don't think I'll see such a day soon, though.

here we have 2, 2, 9, 5, 19, 5, 14, 4, 3, 4,  12, 3, 9, 10, 7 seconds rounds, there are a lot of 2 and 3 seconds long rounds.

I see that a few months ago rounds went from 5 to 10 seconds, so I'm asking wouldn't it be better to have 1 minute long rounds?

Can fast rounds give high MHs miners an advantage since they can exhaust the nonce range even in a very short round?

I'll keep my miner on P2P for a few more days, but if rewards keep being so scarce I'll have go back to a PPS pool or otherwise I feel like I'm just wasting power Sad

regards.

spiccioli.

Does that mean I am better off just running bitcoind rather than Bitcoin-Qt?

Thats what I experienced too, I run bitcoind now.

Thanks. Now, I am running bitcoind.

bitcoind is stable

P2pool seems to crash bitcoind occasionally. Does anyone have similar problem?

Bitcoin!
Is there any plan to pull p2pool support to mainstream bitcoin client?
I know it's kinda too early, but the whole process of mining will be a lot easier to implement, just as easy as old time mining via bitcoin client itself.
I whole-heartedly agree with this.  It might be to early to do it, but not to early to start planning it.

Bitcoin!
For the record, I reinstalled bitcoind and now p2pool can connect to it (even though it's still downloading the blockchain).

Same version? Just curious for future issues.
No, actually the bitcoin version was the problem.  I had installed whatever version is in the main Ubuntu repository (v3.x).  When I re-installed, I added the Bitcoin PPA, and installed v5.x

Code:
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install bitcoind

I am having trouble to create the graphs from p2pool.
I can connect to http://127.0.0.1:9332/users just fine (the data there is json-encoded or something). Connecting to /graphs gives me a 404. I have twisted, zope, pil, pygame installed, but am not sure if rrdtool installed successfully.. Still that silly windows box, you know..
Restarted p2pool after installing those python modules (but didnt reboot the whole machine).

Any hints on what is needed and what isnt?

Is it possible to specify more than one merged URL and pass?

Not yet - It will be soon.

But does it refuse when it doesnt have the blockchain even after it finished loading but still downloading the chain?

No, that's what I was trying to say above.

I got the bitcoind client from git master, and accidentally messed up my blockchain. couldnt get p2pool to work. so i waited for it to sync and then it worked fine.

As far as I understood, p2pool shouldn't work properly while the download is still in progress. It will, however, connect to bitcoind (I tried that a day or two back).

maybe its a specific call that fails...
so it actually doesnt refuse rpc Smiley
