p2pool is PPLNS. Your shares build value slowly and loose value slowly. It's to encourage long term mining. You won't see your maximum payout until a couple block go by, and even then your reward will be split among several later blocks as well.

There's a good explanation with pictures here, http://pool-x.eu/aboutpplns

I'm pretty sure that I'm missing something, but before I move my entire hashing power to p2pool I need to understand why a block yields less than it should and if it actually matters, given the way the shares work in p2pool.

PPLNS pays out your % of shares in the sharechain (not per block).  If payouts were per block pool hoppers would rape p2pool to death.  The sharechain is ~ 24 hours long.  So your payouts in each block will be the % of shares you contributed for the last 24 hours (not that block).  As new shares join the sharechain the oldest shares drop off.  So the payout breakdown at any particular point in time is dependent on the prior 24 hours worth of shares.

This is how any PPLNS (not just p2pool) pool works.  If your hashing power is stable after ~ 24 hours your % of payout should be roughly equal (subject to variance) to your % of pool's hashing power.  If you got 5% of hashing power you get ~5% of the reward each block.

Does P2Pool have Socks4 support today? If not, is it a planned feature for the near future?

If there is something that will make Bitcoin succeed, it is growth of utility - greater quantity and variety of goods and services offered for BTC. If there is something that will make Bitcoin fail, it is the culture of naive fools and conmen, the former convinced that BTC is a magic box that will turn them into millionaires, and the latter arriving by the busload to devour them.

Also: is there any way to switch to a new destination address without restarting p2pool?

Only thing you could do is put the new address as the username on your miner.

That works.

If you want to ensure virtually no downtime, you can start a second instance of p2pool with the new parameters.  It will complain about not being able to bind ports, but this is okay.  Once it loads the share chain, quit the first instance and the new instance will bind to the ports as soon as it can.

Maybe consider lower diff a bit and less longpool messages? I haven't share over last 24hrs...
I have only ~170MH/s and most of my worker get works are break by longpool reset.
In description it is about 10s between longpolls but in most cases i get longpool restart every 5s...
Also after upgrading to 11.1 i`m getting ALOT of dead on arrival (about 30% vs under 5% on 10.3), same worker and config.

Since you have a small rig, it might be worth mining at p2pmining.com.  He runs a public, merged mining p2pool node with diff 1 shares designed for smaller miners.

Aroud 0,015BTC per block. In any other pool i tried it was around 0.0015...

2 expected long term average values for 170MH/s are
(at the moment with a difficulty of 1508589.6720603)
BTC per day: 0.11334309 BTC
Shares per Minute:    2.3749 (1 difficulty shares - not p2pool paying shares)

However ... average expected amount per block will depend on the hash rate of the pool!

Just a comment: these monthly forced updates are not really practical for people who don't engulf their entire lives in Bitcoin. I was fortunate to have caught this update and the previous one because I just happened to check in here.

I will be away for the next 60 days. Hopefully my miners will still be working when I get back.

You can use P2Pmining.com and let me take care of the updates for you.

Yeah, to be honest I don't think p2pool is terribly practical for less serious miners at this stage  Tongue
Hell, I'd gone back to mining PPS entirely before the recent update, which has cut my DOA rate down to a quarter of what it was previously.
Also, look at the luck! I've been using p2pool for a while and I've never seen the 1-day luck go above 100%.
Has the recent update fixed anything?

I am running p2pool with great results on debian, however for best efficiency I am planning on running on a server I have on the internet that runs centos, the debian server I use for mining and it is best not to have the miners and the mining pool on the same server.

I get this strange error when running on centos 5.5
forrestv-p2pool-04283e9]# ./run_p2pool.py
Traceback (most recent call last):
  File "/home/sergio/forrestv-p2pool-04283e9/p2pool/__init__.py", line 36, in _get_version
    if len(dir_name) >= 7 and (len(dir_name) == 7 or dir_name[-8] not in chars) and all(c in chars for c in dir_name[-7:]):

    from . import p2p, networks, web
         ^

Any ideas on how to fix that error, is there a patch available to run p2pool in centos 5.5 ?
On centos python is version 2.4 on debian it is 2.6.6

Python 2.4 is not compatible with p2pool.  Sorry Sad

Getting 2.7 running on Centos is a PITA.  I just had to mess around with it for work and we ended up using ubuntu 12.04 LTS.

I don't know why considering 2.7 is almost 2 years old.  2.6 is in EPEL though.
