I already told you to do all that stuff a month or two ago, if it's the same project we're talking about, heh..  It won't have any impact on memory usage really, but you only need 2 connections on your bitcoind.

Using your settings I had virtually zero transactions.  Sad  That's why I asked...

How does the peering system work and what do incoming and outgoing peers do?

Are the outgoing peers downloading the sharechain from you because they haven´t got the complete list?

What happens when your node has no ingoing peers?


Does your peernetwork automatically grow with your nodes´online time?

I read somewhere that you can also "force" your node to peer with a certain other node, is there a benefit in that?

Does a bigger peer network mean less orphaned shares? (as the found share should be distributed faster around the p2pool network)


Peers talk to each other Smiley 20 peers is enough, but 30 is better... Yes they download the chain if they havent got it up todate. You dont necessarily need incoming peers, but if You can open port 9333 it helps network - all cant do that.

Force connect if theres a node you think is working very well and might help with your dead or orphan shares..

A single peer could easily be better than 50.  There are too many variables.

Upstream inparticular is limited for some people, so if you get connected to a peer downloading the blockchain (and don't have something like Netlimiter), it could saturate your upstream and put you up around 1/2 a second latency to your first hop.  Likewise, a lot of peers that you request the blockchain from will either not send it at all or (even worse) will send it very slowly.  The client isn't aggressive enough in switching peers it tries to download the blockchain from.  Get connected to 8 random nodes & sometimes you'll get crap.

I've said it before, but when I ran p2pool on any server other than nogleg.com, I ran a bitcoind with two connections, one went to nogleg.com, and one was for p2pool.  Probably a better idea is to have three, in case that one goes down or gets DoS'ed or DDoS'ed or something (happened occasionally).  The p2pool client sends any blocks discovered over the p2pool network which I assume is faster than bitcoind the vast majority of the time (compare your p2pool log to your bitcoin debug log & time it to the millisecond, see which one reports it first).  Bitcoind I don't believe is needed except to generate new blocks, getheaders & maybe transactions? Aren't the other blocks also relayed via the p2pool network?

I don't see how such a block wouldn't pay the .5% bonus. The blocktemplate must always include it from the start to make a valid block, it can't be added afterwards or the block wouldn't be valid.
I haven't gone over the source in a long time, maybe it got changed since mid-2012.

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

So if you have 3 nodes on servers, with high bandwidth, manually peering them so every node has atleast two peers should give you a very good performance?

Is bandwidth the limiting factor on peers or is it ping time?

you won't get the .5% bonus for it
I don't see how it is even possible that block finder bonus depends on whether the corresponding P2Pool share is stale or not.

Mine at Jonny's Pool

Hey guys, i have a technical question concerning p2pool.

While shares can quite easily be DOA because of the ~60times faster sharechain, found bitcoin blocks shouldn´t become dead/orphaned that quickly, as they are then broadcast on to the Bitcoin network.

So what happens, when my found share would be a Bitcoin block but the p2pool node considers it a "late" share? Is it still passed on to the Bitcoin network?



Yes, but it won't show up in the p2pool block list, either.... and you won't get the .5% bonus for it, just the "normal" amount earned.

... also why no-submit-stale is bad to use with p2pool.
You're correct about the no-submit-stale settings.  With p2pool you want to submit everything.  You're incorrect about not getting the 0.5%, though.  There's nothing in the generate_transaction code reliant upon whether or not the share is either stale or DOA.  It always divides up the rewards into 199/200 for miners on the share chain and 1/200 for the miner that found the block.

Hope that helps.

cgminer default used to be no submit now its yes submit right?

i still remember setting "submit-stale" : true,

Coin Cadence Front End Update:

1. New hierarchical navigation menu, including global stats, available at top of each page. Categories should be self explanatory (I hope).




2. More data added to found blocks on Node and Miner dashboards, including luck.

3. Miner dashboard now available to all p2pool miners. There are 3 views:

The form:



Report example for off-node miner:



Report example for on-node miner:



4. Payouts per block on the miner dashboard (Miner BTC Reward above) can now be explored for all time with newer/older block navigation on bottom of page.

That is all for this update.

Now that we can view on and off node miner stats next release will include a new data tab on the Global Pool Dashboard that includes all miners, active miner expected payouts, and historical payouts for all time. Also hoping to work out estimated miner hashrates from June 11th onward.

Fun p2pool fact: Since inception 11,296 unique addresses have mined on p2pool and received a payout.
