Re: P2Pool vs Normal Pool - Which one better ?

If you are talking about the rewards, give it at least 6 months, both of them will have more or less the same payout for the last 6 months. Most normal pools have fees which can result in p2pool having more payout. They also have email notifications which alerts the user if the hashrate falls below X.

Is there any reward for the P2Pool owner ?

Some of them run it for free for others. Some people set up their own nodes and mine it on their own node as it have less latency and traffic.

So, unless a P2Pool owner has his own mining equipment, he's not gonna profit from this ...right ? Because, like a normal pool owner, he cant charge ...is not it ?

Unless you impose a fee and people are still interested to join it which is unlikely.

Is it possible at all to impose a fee on mining payout for a P2Pool ?

Yes, if you run this command,
screen -d -m -S btcp2pool ~/p2pool/run_p2pool.py (username) (Bitcoind password)
It will automatically donate a small amount of the miner's revenue to you.

Thank u so much ...u have been very helpful

Do u know if a pool (P2Pool or normal) can be setup on Google App Engine ?

I don't really think this is possible, it is also quite expensive, try buying a dedicated server or VPS to host it. Their official website is http://p2pool.in/

Appengine provides daily 28 instances for free. I'm running some of my low traffic sites over there. I heard P2Pool does not take much of server resource ...so I thought we can run one for free on Appengine.

I don't think the resources would be enough for you to host a mining pool, they require a higher specs and maybe ddos protection, I also don't think it can run on Google app engine.
