For higher hashrate miners, is it suggested to manually set the difficulty in cgminer (with p2pool), or does it not matter?
For example, right now my cgminer instance is running at around 42GH/s. It has set the difficulty to 8. Is there any reason to set it higher than that? Reduced bandwidth/latency? My miners are on the same LAN as my p2pool but a different box.
Every share you send back to p2pool has to be processed by p2pool also.
If when you were mining at 1GH/s and 1diff was ok - then now at 42GH/s ... 32diff should be fine and a good reduction in traffic and work for p2pool
