Solo.ckpool.org website states it is extensively connected to high-speed, low-latency Bitcoin nodes for rapid block change notification and propagation.
Public-pool.io have not found a block, looking at their website. They also do not mention anything about the pools performance.
may switch my bitaxes to solo.ckpool.org based upon past performance. I would not be fussed about a 2% fee if I find a block!
