I'm seeing only 84% efficiency with mine. What settings are you using? My miner name has +256 appended to it. A poster in the BFL forums is using /6000 and is getting results more like yours than mine. Given that share difficulty is only 1080 as I write this, though, wouldn't setting difficulty too high risk throwing out valid shares?

What would be a good input to have to guess how good these ASICs are would be people comparing what their efficiency was with low-latency mining devices (GPUs/Icarus/Cairnsmore1/Ztex/...) and what is their efficiency with their BFL ASIC without any p2pool node reconfiguration.
If they have a mixed setup, knowing the total hashrate of the low-latency devices and the total hashrate of the BFL ASICs can do too.

Warning: don't use different payout addresses on your node: it currently adds latency in the P2Pool process and would lower efficiency.

Currently they don't seem horrible: 84% efficiency is the worst I'm aware of. It's bad but not far from what is good enough to make it almost as good as most pools (I consider the 90-95% range to be where P2Pool starts to be the best solution for mining).
Try to tune your setup according to my guide to see if you can reach a better efficiency (see my sig).

I've done that...average bitcoind latency seems to be hanging around 300 ms since the upgrade to 0.8.2.  With 0.8.1, I was seeing multiple-second latencies.  Over the weekend, efficiency went up slightly to around 86%.  I've switched from +256 to /6000 to see if that makes any difference; it's only been running a few minutes, but the 204 rejected shares to 642 accepted shares so far isn't much different than what I was already getting. I double-checked my router QoS settings; p2pool traffic is running at a high priority.

One thing: my P2Pool node is at home, but my Jalapeños are at work. Ping times tend to run 30-50 ms; both LANs are connected through Cox. Would even this little bit of added latency be enough to throw my efficiency into the basement?

By "don't use different payout addresses," are you suggesting that I should use an address from the bitcoind wallet, or only that I shouldn't use the "mine-to-the-address-in-the-username" feature (which I don't use)?

In any case, it looks like I should see some benefit from the upcoming changes to P2Pool. I'd like to see the concept succeed, so I think I can stick with it at least a little while longer.

Sorry about the confusion and your time spent writing a long post - the sharechain length is set in terms of number of shares, not time, and I meant that the number of shares (8640) will remain the same, so you have nothing to worry about! The new sharechain will indeed be 3 days long.

NICE!!

Thanks!!

According to zvs results in a similar setup, no: he achieved high efficiency with much higher ping times (and one other user reported high efficiency at around 30ms too).
Can you find out if your network connection has some headroom left? The most reliable way would be to monitor your P2Pool host public network interface with a low monitor interval to detect spikes under the 10s interval, then check what your network usage is by graphing the data: spikes up to your downlink or uplink max capacity should be the exception.

By "don't use different payout addresses," are you suggesting that I should use an address from the bitcoind wallet, or only that I shouldn't use the "mine-to-the-address-in-the-username" feature (which I don't use)?

If you have only one miner you are using a single payout address whichever way you configured it. If you have several miners, either use names to connect to the P2Pool node to use its configured (or automatically generated, but not advisable) payout address (my preferred configuration which makes nice graphs for each miner) or use the same address for all miners (if you don't want multiple graphs).

In any case, it looks like I should see some benefit from the upcoming changes to P2Pool. I'd like to see the concept succeed, so I think I can stick with it at least a little while longer.

These are world changing indeed. I've always felt that 10s interval was a bit low (and argued about it with forrestv on IRC in the early days of P2Pool IIRC) but this was a compromise (new miners will have to wait a bit longer to get their full payouts with the new 30s interval). The dust removing and payout computation delay are very nice too.

In fact I believe that most node efficiencies will converge to 100% with these changes which is really good (although it will probably reduce my income as I'm in the 110-115% range most of the time...).

As tuning P2Pool/bitcoind won't bring much benefit this will help with people still insisting on running nodes generating low block sizes and make our income even slightly higher. This could even deprecate much of what I spent quite some time writing in my guide :-(

Hi has anyone Problems with Bitcoind connectet to other Bitcoind nodes over Tor and connectet to local p2pool?

nload says my P2Pool node (running just bitcoind, P2Pool, and cgminer & CryptoSwitcher (the latter two for GPU-mining altcoins)) is averaging 1.04 Mbps upstream, which is about two-thirds of what's available to me IIRC.  This is with P2Pool reporting 7 outbound peers and 12 inbound peers.  Should it be using this much bandwidth?

It is most likely Bitcoind not p2pool. My bitcoind was using nearly all of my 2mbit upstream, so I lowered the maxconnections variable from 125 (default) to 20 and it dropped that down to around 200kbps. I haven't noticed any increase in orphans (or bitcoind latency) with the change.

That's exactly what I recommend in the guide. Lowering the max number of P2Pool connections to 12 (4 outgoing, 8 incoming, which I'm currently testing with no measurable change in efficiency) would be safer too with salfter limited bandwidth.

In the next couple days, I'm going to release a hard-forking change to P2Pool that will make the following changes:

Global changes
* Increase last transaction extranonce length from 4 bytes to 8 bytes, so full 4-byte Stratum workunits can be efficiently generated (which will prevent the need for the avalon branch)
* Delay payout calculation 1 share so that payouts can be calculated ahead of time, reducing latency between a new share being received and work being distributed to miners
* Option to set a "dust target," which increases your share difficulty so that you don't get payouts below that target

Bitcoin network
* Increase SHARE_PERIOD (average time between shares) from 10 seconds to 30 seconds, in order to make it more fair for high-latency miners (read: ASICs)

Litecoin network
* Decrease SPREAD (number of blocks a share's payout is spread over, on average) from 12 blocks to 3 blocks, significantly decreasing the dust payouts generated for miners who get a share less often than every 3 blocks the pool finds

Warnings will be spammed to miners (UPGRADE REQUIRED) once 50% of each P2Pool's mining power has upgraded and the changes will take effect 12 hours after 95% of the mining power has been upgraded, as usual.

If anyone has any recommendations for additional changes or comments on these, please respond.

YES!

Guess I'll be able to throw a few Gh of reduced variability your way after all!

When I was running my local node, my bitcoind had 1 maxconnection, listen=0, and connected to my germany server.  p2pool had 6 outgoing and default incoming.  i don't think i ever ended up with more than 10 incoming though.  i shut it down after a day since I was still getting around 1-2% DOA, but also about 10-15% orphans...  which was more than the typical 5% DOA and 3% orphans or so I got mining to my remote server.

I think if I tried it again it would be with the 1 bitcoind connection and 3 p2pool connections, one to my server in germany, one to my server in jacksonville, and one to my friend's server in quebec.  i suspect this would cut the # of orphans, maybe down to 10% or so...    this assumption for when my link is performing fine 24/7 instead of when bandwidth is oversold like it is now

I restarted server roughly 3 1/2 hrs ago, at 4:40PM local time,

here is what my link has been like since then (I started the ping about 30 minutes before restarting the server):



it is scaled to 400ms and 10% packetloss.  the top bar is jitter (scaled to 50ms, goes off the chart a lot).  note that this is a ping to my first hop, so to get the ping times to my server, add 150ms to that

in this time the server has gotten 29 shares, 0 orphans, 4 DOA.  17 of those are mine, and 2 of the DOA are mine.  12 are others, and 2 of the DOA are them (1G8D has gotten incredibly unlucky with 2 DOA out of 8 shares, even though it looks like his DOA rate is only about 3% to server)

anyway, even my 11.5% DOA or so would have an efficiency of well over 100%,  with that ^^ crap link shown above

OK, so I've been looking at my orphans for the last 10 days or so.... about 33% of them occur after a block solve.

i guess i should also mention that 50% of them are orphaned by

1CTgYxMTY5j6SLytKeMsBWAXuUc6yNKcAe

and i know he isnt using an asic, so why so slow?

How do you know it was that address, and is it wrong to assume that you have his ip address? If so ban him don't send any more work his way. Not that it matters but that address has a huge balance by the way...

nah, he's a major contributor to p2pool.  i think he's been mining it for years.   i'm just whining and wish he had a faster setup.  =p

I don't even know what IP he mines to, which I guess is part of the problem.  I think he's on a private node, probably with just 6 outgoing connections.

oh, I know it was that address since my orphan showed up in the 'headers' list... then I go to the parent share and click on child, and it shows what replaced your orphaned share (if it works the way I think it does, that replacement is actually dictated by the share that comes after it)

Here's another good example (not my shares):

(presumably two would have been orphaned, anyway, but..) These three shares, in order of time my server saw them:

Share 5573d59d Parent: f923ec04
Time first seen: Tue Jun 25 2013 03:26:34 GMT-0500 (Central Daylight Time) (1372148794.021445)

Share d0a23adf Parent: f923ec04
Time first seen: Tue Jun 25 2013 03:26:34 GMT-0500 (Central Daylight Time) (1372148794.186212)

Share 22d14440 Parent: f923ec04
Time first seen: Tue Jun 25 2013 03:26:34 GMT-0500 (Central Daylight Time) (1372148794.205658)

(183ms apart)

got orphaned by this one:

Share 7cb9dbd5 Parent: f923ec04
Time first seen: Tue Jun 25 2013 03:26:48 GMT-0500 (Central Daylight Time) (1372148808.8004)
Payout address: 1CTgYxMTY5j6SLytKeMsBWAXuUc6yNKcAe

14780ms late

it got orphaned because the next share was:

Share 5ccfc4c1 Parent: 7cb9dbd5
Time first seen: Tue Jun 25 2013 03:26:51 GMT-0500 (Central Daylight Time) (1372148811.190973)
Payout address: 1CTgYxMTY5j6SLytKeMsBWAXuUc6yNKcAe

.......

that's a really long lag time..    I was thinking he must have been working on a different parent share, but that says they all have the same one.... *scratch*

oh!

I bet it was caused by this:

http://blockchain.info/block-index/394604/0000000000000099ea7426c7e7289e03c25caebe329b5f0b7f10696d20626879

the same thing I was whining about =p

someone make a ready-to-run, easy-to-configure p2p-pool-node for raspberry.

put image on SD, insert, boot up, enter essential node stuff (.pdf format how-to supplied on d/l page), point miners - go!

I am a bit afraid of memory and cpu requirements of python for rPI - I was thinking about google  golang implementation.
Not much progress yet, but maybe ... GO!

There's no way you could run bitcoind and p2pool on a Raspberry Pi and still expect to have a decent latency.

Indeed. 1GB RAM would be barely sufficient...

Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).

someone make a ready-to-run, easy-to-configure p2p-pool-node for raspberry.

put image on SD, insert, boot up, enter essential node stuff (.pdf format how-to supplied on d/l page), point miners - go!
There's no way you could run bitcoind and p2pool on a Raspberry Pi and still expect to have a decent latency.

Indeed. 1GB RAM would be barely sufficient...
Interesting...

What's really interesting, is this is now a virtual machine as the previous hardware it was running on I needed for something else, and my latency went down and the efficiency went up. (go figure) However the virtual machine host is the same hardware specs as it's previous home (16 processor, 32 gigs mem, sas14k drives)

Here are the specs for the VM:

CPU -- Current Allocation 2
MEM -- Current Allocation 2048 MB
DISK -- VirtIO 30 GB.
NIC -- VirtIO -> br0 -> p1p1 (82571EB Gigabit Ethernet)

I'm not even gonna try and pretend I know wth that is all about Wink


Give me Btc: 1BRkf5bwSVdGCyvu4SyYBiJjEjbNiAQoYd Mine on my node: http://ask.gxsnmp.org:9332/

I might try this for my p2pool node with an eMMC NAND module for storage - http://www.hardkernel.com/renewal_2011/products/prdt_info.php
