Question for some one cleverer than me:

Will the user who's flooding my node with high DOA's have any affect on my nodes performance or any other users income?

If not, I don't mind leaving it on, but if it's affecting other miners income, I'll have to ban it - but I'd hate to do that.....rather help him/her get it sorted.

As long as your server can handle the load of all the combined miners it should not be an issue.

Have the same problem on Coin Cadence, very high DOA, absolutely kills the node efficiency stats...

... Essentially, you can blame dead shares on your miner configuration and orphan shares on internet latency.

I'm going to look into providing efficiency stats on a per miner basis.





and it's reasons like this why orphan % is much more important to look at than DOA, if you're mining on some p2pool other than your own.

every "guide" i've seen either says to select the lowest latency p2pool or whichever is 'closest' to you.  *boggle*

my lower orphan rate on my germany server more than made up for the near zero DOA I got from running locally.  it's simple to calculate expected DOA %'s based on latency, as long as there is little to no packetloss (should be less than 1%)

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).

Is there anything that can be done to improve the latency slightly, some formula or rule of thumb, on a p2pool miner other than moving it to a colocation on a 10 or 100Mbit/sec connection?

Thanks,

Where do I find my P2Pool logs, I am running Linux (OpenSUSE).

thanks,


In the directory where run_p2pool.py is located, then cd to ./data/bitcoin, or ./data/litecoin, etc...   You should see a log file in there.  If you are going to manipulate (edit) the log file, you should make a copy and use the copy.

If you are mining on P2Pool.org you are paying a 100% fee!

I was afraid this might happen...

After 2 weeks of being pointed to http://minefast.coincadence.com with instructions to switch nodes, and an additional week of being completely offline I restarted the p2pool node at p2pool.org at a 100% fee, there is still over 800GH/s mining there.

On Thursday when we launch the new site it will become apparent why we are running p2pool.org at a 100% fee.

Anyway, if those are your miners and you do not want to contribute 100% of your mining power to p2pool.org, you may want to move them to another node Wink

P2Pool Latency & Optmization

Q: How do see what my p2pool's latency is and optimize it?

I have seen seen stuff listed under an OLD thread here "called FUD or something" but I guess the real question is how do you know exactly what the latency is?

My Neppy and P2Pool are connected to the same physical network.

Sorry and just to clarify, I should be making 0.02x ~ 0.03x bitcoins with my neptune right?
What happens if I start only make 0.007x in bitcoins?

My Neppy and P2Pool are connected to the same physical network.

Primarily when people talk about latency in regards to p2pool they are referring to the time it takes for your miner's data to reach the node you are mining on. From what I've read you are running a local node, and therefore should have very low latency.

Latency can be determined by sending a ping to the p2pool node from where you are mining.

Additionally, latency can refer to the distance (not physical distance, but time on the network distance) between your node and other p2pool nodes it is connected to...

Just a note for those in Australia and on my node. I've now added Matt's relay client to both AU and SG pools and have finished with some tweaking that has caused some instability of late. It should be much more stable going forward.
If you are in Australia I believe my node is the best performing and seems to have the highest hash rate. If you are in Australia come check it out, you can get to it from my sig below.

@smoothrunnings, I'll try to answer all of the questions you've asked.  Hopefully I don't miss any.

Latency for your miners is not an issue in your case.  You are running a local node with both the miners and the node on the same physical network.  Latency between your node and others is unknown to me.  You can check it by pinging the nodes to which you are connected.  The latency between your node and others is important because the faster you can propagate your found shares, the better the chance they aren't orphaned.

You can also help ensure you're getting BTC blocks relayed as quickly as possible by using Matt Corallo's relay node.  Check it out here: https://bitcointalk.org/index.php?topic=766190.0.

Regarding your question about earnings, I've got only one word for you: variance.  Sometimes you're going to be unlucky and not have very many shares on the chain.  Other times you're going to be lucky and have more than you should.  Also, you need to remember.  You are comparing earnings per day to earnings per block.  Online calculators report earnings per day.  As of right now, your 3TH/s expects to earn 0.05058BTC per day.  Your node reports expected payout per miner per block at that particular time.

The simple fact is that p2pool is going to be affected by variance because of its relatively low hash rate compared to the rest of the network.  In addition, you as an individual miner on p2pool are affected by variance because of the nature of finding shares.  It's a double whammy that leads to significant swings in earnings.  I'll give you a concrete example of this.  On 9/10, p2pool found 6 blocks.  I also happened to be on an upswing and had more shares than expected on the chain.  I earned 0.26259819BTC that day (an average of 0.043766365BTC per block).  Way more than what I expected to earn for my hash rate from my 8 S3s.  On the other hand, p2pool found only a single block on 9/12.  That day, I only earned 0.03200959BTC.

Here's another example.  I got a co-worker of mine into BTC and he currently owns an S3.  He's currently mining on my node and hasn't found a share in over 5 days.  He's missed out on 10 blocks so far.  I hear the same thing from him constantly, "What's wrong with my miner?  Why haven't I found a share?  Should I reboot it?  Something must be wrong!  I'm going to switch to another pool."  Then I show him that even with not receiving payments for some blocks, he's still ahead of expected earnings since he's started mining on p2pool.

In short, it's all about the variance.  If swings in luck are too much for you to deal with and you want the comfort of seeing lots of small, regular payments adding up, then p2pool is not for you.  I'd suggest one of the more traditional pools.  Otherwise, sit back, relax and enjoy the ride.

I'm thinking of switching to P2Pool but don't want to run my own node. I've looked at the node list and some like p2pool.org seem like scams. Can someone suggest a node in the southeast i"m in Charlotte NC? Would be running about 10-15TH depending on how I decide to split it. Thanks

It's generally seen as best to run your own node. However you can try looking at the list here for one that has good ping times/location to you.

Windpath has his node in VA.  http://minefast.coincadence.com.  By the way, p2pool.org is not a scam.  Windpath owns that domain now and is turning it into an informational site.  There is still a node there but unless you feel like donating your hashing power you probably don't want to mine there since it is 100% fee Smiley

So, Windpath's node at minefast is a zero fee node? I pinged it and the times were decent. I see the 100% fee node is also in Ashburn VA same as minefast. And another question, 6 of my machines are Dragons that don't properly execute the stratum protocol. How would I set the difficulty or are they not compatible with P2P?

Thanks

http://p2pool-nodes.info/ Search here for an US node where you have the lowest latency. If you don't know what latency is then just ping the nodes from the same network as your miner and pick the lowest ping(measured in ms=milliseconds).

Good luck!
