I grew tired of the comm problems with p2pmining. It's my backup now.
I think I had an epiphany.
I spent some time this morning watching cgminer on both my miners. I watched them mine against p2pmining, and then compared the results against when running against my local pool. I dug out the cgminer docs to see what all the values mean on the screen, and if I'm interpreting this right, I'm wasting resources trying to mine on p2pmining. Maybe I'm missing something, which is why I'm posting this here.
First of all, efficiency. On p2pmining, I never saw above 10%. I was lucky if I saw 5%. On one miner, I'm at 125%, on another, I'm at 43%. From the cgminer docs:
E: The Efficiency defined as number of shares returned / work item
Second of all, utility. From the cgminer docs:
U: The Utility defined as the number of shares / minute
On p2pmining, for one box I was around 4/m, on the other 7/m. Locally, I'm at 8.8/m and 24.6/m respectively.
And of course rejects. I'm at 1% or lower locally. I've been around 10% on p2pmining.
Yes, p2pmining gives merged mining. But it seems to me merged mining on almost worthless currency, compared to btc, doesn't come close to compensating for the efficiency I'm getting from mining locally on my own pool. And I already have a namecoin server up and running that my local pool is pointed against, and nmc seems to be by far the most valuable of the other currencies.
Am I missing something, or does it seem like I'm wasting resources mining on p2pmining? I've got about 2.4g/h, with about 100m/h being routed right now to p2pmining as backup as cgminer dictates.
