I have a question, I have setup 2 nodes one has my S1's hooked to it and the other has my S2's attached to it, they seem to hash a lot better doing it that way. If I have them all on the same node my total hashing power decreases, will the slower hashing of the S1's bring down the S2 hashing rate or does it make no difference? Are there any pros or cons of running 2 nodes?
