I just created a new p2pool node scanner at
nodes.p2pool.co. The other ones were either too buggy and even at the times they were not I still could never figure out which p2pool to mine. How much does latency matter over "efficiency if no miners"?
So I created the P2Pool.co Node Scanner. I think it is the best P2Pool node scanner out there.
It includes a scoring algorithm to highlight the best p2pool near your location, and it factors every datapoint and combines it into a p2pool score.
The latency numbers are much more realistic than other node scanners (compare our latency numbers to actual pings that you run yourself and compare them to the other p2pool node scanners).
If you would like us to add your node or if you have any ideas to make this scanner better than PM me.
