Hmmm... one of my machines is at 5% stales, the other is at 19.5% stales, I'm beginning to wonder if it is some sort of network congestion since one is connected to a higher-priority switch on the network. Also, the one with lower stales is on cgminer 2.3.1, higher stales is the newer 2.3.2.
A couple things for p2pool you want to be on 2.3.3 or higher. Some of the older versions have a bug where cgminer ignores the submit-stale flag set by the pool. Discarded % is irrelevant. It is the amount of work cgminer requested that it discard BEFORE starting to work. This is simply a metric between GPU hashing power and LP interval. If your GPU is 300 MH/s (each GPU is what matters) then it will complete a getwork in ~15s but LP will occur early than that so most queued up work will never be started. You can reduce the amount of discarded work by setting the queue param to 1 (and threads =1) but you will still have a lot of discarded work. One other thing to consider is some routers have an issue w/ high # of open connections (especially multiple rigs all running cgminer opening dozens of simultaneous connections). newer version of cgminer helps this but some routers still lag under the load (# of connections not bandwidth). OK, thanks. I'm updating cgminer now. I booted up guiminer and it shows 0 stales after 50 submitted shares but it shows "connection problems" every 10 seconds instead of 350mhash so this may be a network thing. Thanks for the help. new cgminer didn't fix it, though I am down from 20% stales to 15%... switching to guiminer for a few hours to test I've been on guiminer for a few hours, stales are at 7.5% and dropping. Anyone else on guiminer getting the "connection problems" under gpu speed? Another thing, GUIMiner shows 0 stale shares, but the site is still showing a percentage... any ideas why? |

ack, I'm at 20% stales... I'm trying intensity of 4 to see if they go down but I'm only mining at 85% of capacity with such a low intensity..... is it possible to mine one thread on one pool at a certain intensity and another thread on another pool at a different intensity (in cgminer) ?
Didn't work... what's going on? What am I doing wrong? There can be multiple reasons. Is your network to congested for Longpolling to keep up? Is your cgminer updated? Did you try mining with only one thread (-g 1)? What is your hashrate? I don't think I waited long enough, the 4 intensity ended up getting my stales to 5-7% but I'm running at about 85-90% of full speed, which I guess I'll just deal with. When I look at pool information it says that I have 7000+ discarded work due to new blocks, is this normal for an 800MHash machine after about 48 hours?

Asking for 60% is a bit high.
I think it depends on the debt. I really don't think this will work with a one-size-fits-all rate for debt purchases. Otherwise, there's nothing to stop me from creating a fake account, lending it some bitcoin, claiming default and then on-selling the debt here for 20%. Some debt is worth more than other debt! Yes debt has different value. However, I was looking up debt collectors in the U.K. and they typically charge between 10%-20% depending on the difficulty. Granted, bitcoin debt it a unique animal, but I think if Kaos advertised a range or a maximum purchase price, he could make quite a bit of money. Especially with that DI debt.  |
