Problem is p2pool is virtually unusable at this level with little guys like me.  12gh/s and estimated time to share is 18.6hours. Sad

M

There is good news:  The hashrate of the pool is dropping again.  You'll get more shares more often.

However, there seems to be some bad news:  The hashrate of the pool is dropping again.  There won't be as many blocks found as often.

One year ago it was supposed that p2pool had to be split at around 1 TH/s , today it was at 60!

ps. btw, you can always move to HHTT which needs hashers and where you can set your difficulty to a much lower level.

Yeah, I know what you mean. That's why I've configured my node as a low-rate-friendly node to reduce the share variance for each individual miner. Check the link in my sig for details.

The common garden variety bitcoin miner is a fickle creature; one minute they turn up crying about DOS, next minute they're all gone again, as if DOS has suddenly become impossible. Anyone would think you can ROI your equipment on a Big-Hash-Pool during the 24 hours this mini panic took place.

I'm really looking forward to the return of the days when mining was inhabited by more people that are motivated by Bitcoin's success than by people that are only interested in their own success. And the sad thing is they're either (or both) too lazy or conservative to get that their outcome at p2pool could easily outperform Big-Hash-Pool, but maybe that will come into focus a little more once the transaction rate further saturates the current upper capacity.

Is there any sort of "front end" that you can connect to by name, that finds the fastest/closest p2pool server to you?

The p2pool server daemon itself sort-of does this already, since it connects to multiple other nodes.  Having a node in your own network is the lowest latency solution for the vast majority of people, and even if a front end existed that would find the lowest latency public p2pool node for you, it would take about as much work to set up and maintain as the actual p2pool daemon takes.

I could see a use for this, though, if you couldn't guarantee the availability of your p2pool node even within your own network and didn't want to statically assign a list of backup nodes into your miner.  Still, it's one more point of failure, unnecessary complexity, and you'd still better have a static list in case your auto-connect front end fails.

well, first off, to OP:  fastest =/ closest

well-connected european nodes will have less orphans than nodes in western hemisphere

when I was running a local node, I had an i7-960, 24GB RAM, had the whole bitcoin blockchain stored in RAM, getblocktemplate latency <1ms, but it still performed worse than either of my european servers because of orphan rate

probably not so bad now that shares are farther apart

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).

I dunno lenny dude, it looks and sounds like a mighty fine setup alright. But when I think about it, it's a whole lot of power & expense for little to no performance improvement. Don't get me wrong, it's great - but I would have expected better performance looking at your latency graph (although I do agree with zvs - there's far too much emphasis on latency for some reason, it's not as important as most people think, I think).
Looking at your setup & comparing it to my cheapo budget thing, you've got twice as many cores using 50% more power & twice as much RAM running at 50% higher frequency - but the end result doesn't seem to be much different to my graph:



I'm also merge mining 6 coins - but I think you are too, am I right? Is the 1mb block size the only bitcoind adjustment you've made?

Peace.

I'm getting better latency, though I am only merge mining NMC.  Machine is an i5-3570S (the low-power 3.1/3.8GHz), 16GB DDR3-1600, and 2x250GB Samsung 840 SSD.  Running on Windows 8.1.  Machine also runs BFGMiner for all my mining hardware, is my home NAS, downloader machine, VM host...

I'm using a crappy old Intel 320 series 40GB SSD for the OS & a 120GB HyperX SSD for the wallet data, but my setup is solely for headless mining.

Edit: I'm actually amazed at how good these Sempron 145's are when they are unlocked - with such little power.

This is a do-it-all machine, so I didn't mind spending the cash on the drives.  They do the p2pool stuff, they host up to 8 VMs, and they use less than 1W when running.  The big data for the rest of the house (movies, TV shows, Music, etc) is stored on a pair of 4TB 5900rpm drives which spend most of the day spun down. 

It's about as power efficient as I can get it - 430W 80Plus Gold PSU, Asus B75 chipset board, 65W i5, integrated iGPU - it's a fast machine considering at full chat it only uses 80W.  Typically it's around 50W.

If I setup a p2pool node and want to make it available to public (well it is already available to people who find it :p), is there a list of p2pool instances (for LTC and BTC) somewhere?

Hey all, I have a question.

I am merge mining NMC, but where exactly are the payouts going to go to? To the NMC node's wallet? Can I specify a specific address somewhere? There's literally NO info about this anywhere.

I think the reason you are not finding this documented in the P2Pool stuff is because it's not specific to P2Pool.  I assume you are merge-mining to a namecoind running locally on your machine?  If so, if/when you get a block, the namecoind will send the payout to you on an address it created.  If you then run 'namecoind getinfo', you will see the mined coins in your balance.

Thank for replying. You assume correctly about namecoin running locally.
So what you are saying is, there is no way to actually specify a payment address, it'll just go to the NMC node like I assumed it would.

Guys, I don't know what's going on but I haven't had a payout in a long time. I think P2Pool version has moved on and I'm sitting mining on my own. I haven't had the time to pay attention recently but every time I've looked at the p2pool screen, it's been happily scrolling along with no apparent warnings. I have no problem with upgrades, I have no problem with obsoleting versions but when we do it, could we make it a bit more obvious, please? It's one thing to pay out more or less than other pools but if you're not paying out at all, that's going to put a dent in things pretty quickly. This is not a demand, just a courteous request. I don't have --give-author set to 0 so you're sharing the love.

In the days before the switch, your P2Pool instance would have been displaying a lot of messages and warnings about the impending change, but once it's happened, your instance is alone with only the other nodes that didn't upgrade and there's no easy way for it to know that it should have upgraded. (I suppose it could see that there are lots of peers with higher version numbers that refuse to talk to it...)

You should subscribe to the mailing list mentioned in the first post if you don't obsessively monitor your P2Pool daemon.
