Alright, looking through the source code, the problem is that the recent_blocks resource only gets populated with the last day's worth of blocks. So it's not the frontend's fault. If it could at least track a minimum of, say, the last ten blocks that would be a bit more helpful when we run into large blocks. Then I could modify the frontend code a bit to calculate "Current Round" based on the last block solved.

I'm just trying to reduce the number of tabs that are constantly open in my browser, heh.

I think it's a good idea. I've wanted some of the features that the p2pool.info site have but that aren't in the p2pool frontend (even the aftermarket one).

Block been found recently thankfully.



Over the next few hours I'm pointing a Jupiter, Saturn and a Mercury all at p2pool for testing on FW 0.98.

Jupiter already seems to be happier than it was last time, Saturn will move over soon.

hetzner network was screwed for about 15m, if anyone reads this that was mining on my pool or some other one located on hetzner network

oh, and luck over the last 3 days has been good if you include 266856 and onwards  Grin

5 blocks in 76 hours, estimated time is 14hr30m but that's with 32.9 thash, and the average over the last 76 hours is probably more like 29-30thash...  jaja

btw: whoever is using p2pool.org:9332 and paying 2% for 75% efficiency... stop!

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).

Yes .98 is much better. I'm up from 440GH/s to 530GH/s on my Jupiter.

heh, speaking of which...  i just noticed all the DOA, and it looks like i have nearly 1000 python connects from one person.   not sure if something is just busted or if it's intentional or not, i guess i might reset p2pool.

alright, I don't think it was an actual miner, since when I firewalled the IP, nobody's activity dropped off...   but the 600-700 open sockets in python weren't closing, so i used fuser -k (then some 600 connections went from established to FIN_WAIT_1).  surely there is some better solution?  anyone that has more knowledge of linux?   was there any way to get rid of all that w/o having to restart p2pool?

i added some limit to simultaneous connections in firewall settings anyway

it was 220.233.90.xx, some ADSL connection from Australia

& having the stats reset sucks.  0 orphans in the last 24 hrs, and 1 out of like 200 shares =p

ah, nice to have backup pools set, never know when someone might DoS a p2pool to take that .001% hashrate out of action.

 i think you have the wrong person though, since if you look at my weekly chart, FTX has been on it for 3 or 4 days =p

Yeah, the top chart is your pools stats, I was just showing the chunk where it was blank and was on my pool it seems.

I was confused more than anything who it was Cheesy

I have also set up a private p2pool node on Azure testing a Mercury which is running very nicely atm.

Hy,

i dont know... can i set the p2pool node to a pool node for p2pool network?



So the Miner makes shares for the Node, and when there enough shares, they make a p2pool network share.

All Miners on the node become % of the share. based on there shares to the node.

p2pool payout to the node wallet, and a option for weekly payouts, or the miner can set it over there user name.

e.g. : *Bitcoin-Wallet*/+P0.1   for Payout when the miner have 0.1 btc

Just a heads up that from the 40 nodes I can see right now; 24.161.35.225, 184.56.251.69, 183.136.216.39, 24.10.44.25, 183.136.216.39, 95.128.48.209, 193.190.255.150, 38.109.218.101, 198.91.172.112, 209.195.4.74, 186.220.27.239 all have over 1MB of transactions stored (while most everyone else in this lot has 45kb).  That's why your bitcoind latency is so high.  Some of these nodes are essentially dead, but others aren't...

Upgrade your bitcoind version, you're probably picking up the horse staple battery transactions... or lower maxblocksize to something like 250000...

oh, btw, 24.161.35.225... very impressive system there, the other five I looked at had latencies from 2s to 6s, yours is hanging out around 0.9s...

www.nogleg.com:9332/peer_txpool_sizes

Look in the p2ool/web.py file and you'll find all the things you can query.  ed: I pulled that earlier list off my other server that I use as a relay, it connects to 40 random nodes, w/o using --p2pool-node, so it tends to get a bunch of duds; p2pool nodes that haven't been updated in a couple of months.

zvs ,You seem to be really switched on , I was wondering what would cause the spike in latency in my graph.

I'm honestly not sure about those.  My guess would be that it's a large transaction that's being forwarded to your p2pool to store, but I'm not sure....  think it also occurs occasionally when blocks are solved.  The gradual increase is normal the longer it goes w/o a block being solved (all these transactions being stored)....

Now, my question... why does it report a much larger DOA rate in my log file www.nogleg.com/log then it does on the website?  

www.nogleg.com:9332/static

Also, is there some significant drawback to submitting a share twice?  I assume the second (or third or fourth) counts as a DOA, but ... wouldn't really be a DOA, since the first one would be the one that mattered?

Is that why there's like a 20% discrepency between the DOA in the log and the DOA on the website?

ED#10: good lord, ok, everything fixed.  now, anyone know the answer to the question?

WANTED: Active dev to fix & re-write p2pool in C

So nice it has been implemented already. But I will agree with comments made earlier on, it should be applied to miners with 500 GH/s (1.7% of total p2pool hashrate). Please reduce it to at least 2% from 5%. It's a simple fix, and it will help a lot to small miners.

From experience, having "only" 2% of the p2pool hashrate doesn't mean there's too much variance (the rewards oscillate +/-~10% around).

With 5%, ~20 large miners can take most of the pie, leaving crumbs to others. With 2%, this is raised to 50 large miners.

I'd be OK with a 1% limit, but 2% should limit complains of high variance from large miners (the reward may even move as much from the hashrate fluctuations of the whole pool as from the share frequency variance, people with 5% or more may be able to confirm this if they have variance around 10% in their rewards too).

BTW: I've not looked into the code, what would happen if there were only 10 miners on p2pool? Is the current algorithm able to converge on sane values or would the current 5% target raise the individual share difficulty without bonds.
From the one-liner extract above it seems there's a missing parameter to achieve this protection (the number of distinct addresses with valid shares in the recent sharechain).

I will decrease the percentage then. Maybe 1.67%? That's a share every half hour.

If there are very few miners, nothing insane happens. Smiley Each miner's share difficulty multiplier becomes the maximum, 30, and then the 30-second share period target decreases the minimum difficulty until there's a share every 30 seconds again.

Has this been implemented yet? I'm considering turning my node back on to see if it improves anything..... Grin

nothing on git yet... there were two changes, but only affecting litecoins and some other bizarre coin  (terracoins?)

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).
