As you know the new Antminer S9 is available and its hash rate per second is 14TH. Now, my question is if I buy one of these, how much internet traffic and bandwidth do I need for mining by pool and how much for solo mining (and is it different for two machines or so).
This question should help you: http://bitcoin.stackexchange.com/questions/360/what-are-the-bandwidth-requirements-of-a-mining-rig

An S9 at the current difficulty could expect to find one block every two years solo mining, under ideal conditions. The reality is the difficulty will increase at a pace sufficient to ensure you never find a block. – brandondoge – 2016-06-06T14:41:37.287
