This is not hop proof.

Set up that user who GHS drop for 30 min or more lose there shares and his shares will be distribute among the users who stay longest.
This will make it hop proof and people will stay or go for good.

I was in P2pool for 6 months and it was the pool that pay the most, but since the bitcoin drop to 200 dollars it just died. If you look at the history 3 block per day and some days up to 5 blocks. I guest those days a long gone. 

Thanks.
It's PPLNS - learn about how PPLNS works - rather than making guesses based on small random samples that are not representative of the population and then coming up with some ludicrous idea about how to screw up a PPLNS pool.

But I guess, more importantly, learn a little about p2pool.
No node except your own node knows anything about your mining except when you find a share-chain share.
So your idea means that any p2pool node with less than something like 20THs will never get paid ... yay good idea there Tongue

I was going to take my time to answer you back, nut honestly I cant waist my time.  You are just dumb to what is going on. The best of luck for you guys.

Yeah, everyone else is dumb. It's surely not you who is dumb.  Roll Eyes You make absolutely no sense.

Get the fuck out and stop wasting "your" time.  Roll Eyes

If you're running a public node I suggest checking your graphs. Some dickhole is spamming work requests without doing any actual mining. It causes massive DOA spikes.





How long ago did this start.  I am the only one on my node and it seems to be doing fine.

Has anyone found anything yet on this.


He might be targeting the larger nodes. I had to whitelist my miners at the firewall to keep him out. It started about 20 hours ago. DOA went from 2-4% to 40-50%. A lot of traffic was coming over tor exit nodes, but trying to blacklist him was like playing whack-a-mole, so one less public node here.


I suspected something was up the past few days,  My local DOA is 4-5 % reasonable, but my efficiency rate is a bot high.  Looks like i should move the Node to a SSD drive.  That usually helps about 5% on the efficiency rating.

Hope he gows away and plays on some one else pool.

Try my skydrive, just uploaded latest win64 builds.

i'm getting lots of these:

This is because there is a java script call from within your index.html, or graphs.html, (or some other webpage filename) where the object being queried is not in your database/data-files.  From the web browser, you should see a share, block, hashinfo, etc.., the data is missing.  If the server version is compatible with the java call, then the fields will eventually fill in with new data, and the errors should recede.  If there is an incompatibility, then the fields will never fill in and the errors will continue.  Not a big deal.  More of a eye sore when viewing logs, or live screen, than an issue.  Unless the errors are rolling nonstop, then the issue needs some fixing.

Greed, impatience & lust for profit can often temporarily blind people to reality, causing them to wander around from pool to pool in search of faster & greater profits, until eventually their vision has cleared & it becomes clear that not only are there no fast profits to be made in mining, but also that p2pool is the highest paying pool there is anyway.

Looking at the Pool hash rate. How do we know this guy with the 1PH of hash has not been hopping.  I do not see any stable 3PH of hash on the p2pool.  Most people with that kind of power are experienced enough to have already found a place to mine that they like and they usually stay there.

As i read the post looks like a childish mixing of words.

I have been studying all the different pools and have found p2pool with my own node to be the most profitable, it just takes allot of patience when shares and blocks are not found.

Thats my 2 cents worth

Keep the boxes mining.  It will get better....

There are many reasons for fluctuating hash rate - testing, failover etc - it's perfectly normal. I'd be more concerned if the hash rate stayed constant..... Wink

First, I really don't understand your reply to my earlier explanation of why your suggestions wouldn't work.  Now you are getting more and more ridiculous with your claims... especially that crap about you having a petahash here.  Do you honestly think that we either don't remember or are unable to use the forum itself to look back through your posts?  You came around here in late January asking all kinds of questions on how to setup a node... how to setup a fee for your node... how to setup your miners to be effective on p2pool.  You were all excited about having 5.5TH/s running on the pool.  That's a VERY far cry from the claimed 1PH/s.

You've been around less than a month and have no concept of how the pool works.  You then go ahead and claim instability in the pool due to pool hopping - which both kano and I have explained to you is not what's going on.  We've suggested you actually learn how p2pool and PPLNS pools in general work.  Your response is to come back and call us stupid and that you can't be bothered "waisting" your time answering.

So go ahead... take your fictional petahash and leave.  Don't let the door hit your ass on the way out.

I could not of said that better Jonnie

Ok one question.  What are other people seeing the efficiency for share on there node?  Mine runs between 15-20% mostly staled shares and every once and a while a single orphaned share.  Was just curious if that's the average most have been seeing lately, the longer the node is running the numbers get better. Was thinking about going to a SSD drive but that's down time and cost.

A good quality SSD will give you superior results. I run my system on one SSD with my wallets data directory on a separate SSD & I get ~0.5 - 4%.  HDD's are pre-historic....... Grin

I don't see how disk performance (within reason) can effect efficiency.  What is effecting the efficiency the most, I think, is the network performance.  Well, also single core performance needs to be there, since P2Pool server is single threaded.  Not only bandwidth availability, but response time between your nodes is key.   Look at your GetBlockTemplate latency.  I think my is very low, with a current daily average of 133ms.  But I have a dedicated business cable line.  Anytime I had any network hiccups, or see increase is GetBlock latency, I see efficiency decline.  And I'm not sure about this, but sometimes I think issues are cause by bad nodes connecting to me.  Not necessarily malicious nodes, but some problem that drives the network usage much higher than with other nodes.

Back to disk performance.  I look at performance reports on my host, which is Linux by the way, and the disk I/O is negligible. I'm seeing less than 10 IOPS to the devices.   Full disclosure.  I am running SSD (2x RAID-1), so you might think a hypocrite.  :-)  But I pro-actively bought them and now realize it wasn't necessary.   The first thing I would look at is the I/O wait time.  If you need some help gathering the data, I can help.  Just let me know the OS.  And also gather CPU and network stats too.

The other thing I want to point out is the -expiry option.  A lot of people have said the setting doesn't matter anymore, but I can't see why.  I've never looked at the code, but the cgminer readme has the info below.  I always change my miners to 1 (all currently Antminer).  When I left it as the default of 120, I got more stales.  I did not run an extensive test though.

--expiry|-E <arg>   Upper bound on how many seconds after getting work we consider a share from it stale (default: 120)

My node is running on a Debian server and the p2pool and bitcoin all are running on all 8 cores.  The server is extremely fast.  My windows test server node is on a SSD drive and it is allot more efficient then the Debian box.

Has anyone Ghosted a Debian box yet,  I have had mixed results with Centos in ghosting.  This is my first Debian box.

Looks like it is time order a new SSD drive.

So what did you set your miners to.  I an setting up 14 new S5 miners this weekend and am running 7 s3 and retiring 6 S1 and 5 S2 if any one wants to make me a offer on the older s1 and S2. there for sale.

Please stop telling people  to do anything but change the queue. Artificially lowering the discarded value serves no purpose whatsoever. Decreasing scan time and expiry are for the dark ages of CPU mining - paying any attention to the "discarded work" value is completely pointless and actually harmful. The only thing here that's making a difference to CPU load is decreasing the queue which they have set far too high by default. Please do not decrease it below 1 though.

Although, as IYFTech demonstrated, using a queue setting of 0 gave better results with Antminers on p2pool, but it depends on your set up of course.

Yes I am doing that on all Ant miners.

Was wondering if any one played with the expire settings and did any testing to confirm or deny the claim.

OK.  My bad on the expiry param.  I won't mention that again.  And my decision to add that note diluted my message about disk I/O, which I still stand by.  SSD's are certainly great, but there is no disk I/O requirement coming from p2pool or bitcoind to make the SSD a necessity.  Most modern filesystems use system ram as buffer cache and the I/O load is so low, it's all cache hit performance.
