I assume you mean 'affect', not 'effect'. What do you mean by 'affect'?

Node-to-node communication over the loopback interface is probably a 
tiny bit faster than node-to-node communication over fast ethernet (100 
Mbp/s) or gigabit ethernet (1000 Mbp/s), but only marginally.

Yes, I have several physical servers which run more than one erlang-node 
per server - naturally using the same cookie.
