Stale rate is still pretty dam high Sad

Code:
Version: 9.1

Pool rate: 335GH/s [b](23% stale) [/b]Share difficulty: 522

Node uptime: 1.640 days Peers: 6 out, 2 in

Local rate: 3.81GH/s (5.9% DOA) Expected time to share: 0.163 hours

Shares: 216 total (39 orphaned, 13 dead) Efficiency: 98.28%

P2Pool release 9.2 tag: 9.2 hash: b016b6b522286e4675b82b9c4206784937977f3e

Changes:

This has been confirmed (more or less) to help reduce your stale rate.

Before the switch DoA was at 1.5%. After the switch it climbed up to 5.2%. The latest fix brought it down to 2.5%.

CPU usage still seems high and p2pool is using 1.4 GB RAM, so hopefully there is still place for improvement Smiley

Comparing p2pool block receive times and blockchain.info times shows that 250 kB blocks are now distributed in 0-2 seconds. This is amazing!

I grabbed the latest git this morning that includes the efficiency patch, that is the big change in 9.2.  After about 14 hours, I'm still looking at 24% stale rate.  However, cgminer is now reporting about 3% rejects, where before it was 10% - 20%.  So I think the stale rate is because of my conn problems.

Was using 9.0 fine and suddenly on reboot was spammed with this message and it closes instantly when using:

Now I downloaded 9.2 just in case, but it connects quickly, but never do my miners seem to connect.. not even on the host machine. Anyone..?

Double verified 100% orphan on 9.2. 20 more shares instant orphan.

9.1 and 9.0 are both fine though...?

Your efficiency is high enough Wink
But you should try version 9.2, the DOA rate is much lower for me.

After 12 hours on v9.2 my stale rate has gone up to 36% - whereas on the previous v9.1-9 it was steady at a lower (but still high) 18-22%. Connections seem quicker, but those damn "punishing share for stale" and "tx" messages are constantly thrown at me. Might go back to the previous build.......

There few parameters you should look at:
1. Local rate:  xxx H/s (yy% DOA)  
DOA there should be very low (max few %). If it is high possible miner config is bad or node GBT/lag is very high and you are mining old share.
2. Shares: xxx total (yyy orphaned, zzz dead) Efficiency: qqq%
yyy depends on mostly LUCK, some on config. Orphaned share means that someone found share at same time as you, and yet another share was put on his share not yours.
zzz depends on node and bit on luck. Dead share means that it is another share already after that one you was mining. So if your node is lagging and not fetching/passing shares fast enough you will get more dead shares.

Hi rav3n,

My local DOA rate on p2pool is 1.8% which is pretty normal for me.

I just done a few tweaks on my rig and rebooted, but before that I was over 36% stales and about 75% efficiency - where as before all this malarkey I was at a constant 98-110%+.

Ki77er, how do you manage to get a 0% stale rate when the pool stale rate is over 20%? Teach me Obe Wan.....

cgminer submits stales automatically on p2pool without any specific configuration (a pool can request stales to be submitted and cgminer honors the request).

P2pool tuning guide
Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).
