[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

[iongchun]

unfortunately p2pool wasted work do not go below 15-20% as was before hardfork

Stale P2Pool shares are not "wasted" - they still can solve blocks and get us all a payout. They're just don't count for P2Pool credit, which affects everyone to some degree, so everything is optimal and fair as long as your efficiency is close to 100%.

Since people will keep talking about this "problem",
how about showing "Local status" on the static page based on efficiency?
Ex. "Good" for >110%, "Normal" for 100~110%, "Below Normal" for 90~100%, "Bad" for <90%.

when I set maxconnections=10 my p2pool is not started, just stay in

Code:

2012-12-09 21:05:51.285000 p2pool (version 9.4)

If it uses up all 10 before p2pool has a chance to connect then this happens. You can either start p2pool quickly after bitcoin or increase it to 20 or something.

Or restart bitcoind after starting p2pool.

Where in my linux p2pool directory can I look to find the human-readable version number, e.g., currently, 9.4?

run_p2pool.py --version

This was while p2pool was already running normally:

Code:

proofer@miner:~/src/p2pool$ run_p2pool.py --version
fatal: Not a git repository (or any parent up to mount parent )
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
unknown
proofer@miner:~/src/p2pool$:

The p2pool directory is renamed from the forrestv-p2pool-6880123 directory that was the expansion of the 9.4 linux tarball.

After 1d 15h 5m 39s, I have 211 shares, 22 orphaned, 3 dead - 11.85% stale rate.  That's using the linux "do not use for mining" build in a VM, and p2pool v9.4.  Decent in my mind, but not as good as it was pre fork.

Between my 3 miners, I have about 112k shares submitted, about 3k rejected, or 2.67% reject rate.  That's pretty good for LP imho.  Looking forward to stratum coming on.

What happens to the roof of the 400GH / s? It seems to be impossible to overcome when large mining brings lot of computing power other small miners disappear.

That's an excellent long term stale right.. I think mine is closer to 5%.

[lenny_]

I have even better stats. On total 13187222 shares, 36281 stale shares = 0.275%.
Using Ztex's BTCMiner on BitMinter pool.
Unfortunately, my p2pool machine is too weak to get similar results on local p2pool with my FPGAs. Bitcoind latency is ~0.5s.

You can't compare stale rates of bitminter (or any non p2pool) with p2pool.  They work differently.

My stratum miner is only .068% reject, but that number doesn't mean anything compared to p2pool.

[mdude77]

I've come to the conclusion that latency plays a huge factor in stale rate.  I think bitcoind was hogging my bandwidth, I turned off port forwarding for it, stopped using -n to connect to multiple p2pool pools, and turned off port forwarding to my backup p2pool.

After 10h 8m 45s, I have 49 shares, 2 orphaned, or 4.08% stale.  Been ages since I've been that low.

[Prattler]

There is still a memory leak. P2pool consuming 2.4 GB memory (RES) after running for 7 days.

I found the same thing.. it is vital to keep that latency down. It makes sense when you think about it too.. if bitcoin is taking 1 second all on its own then you could expect around 10% stales just from that since we have 10s long polls.

Excuse my noobness, but is this for Linux or Win? And how does one get this better "Git clone p2pool" - what's the procedure? I went to the site but couldn't work it out......dur.

I think it's probably easiest to just leave the folder with it's original name.  Doesn't that work?  I seem to recall someone mentioning that a few pages back.

Not if you use a script to start it.  Everytime you download a new version you have to update your script.
