Using Multiple nodes with same Cookie on single machine

You have answered my query.
Regarding effect:I mean we are planning to run approx 50 nodes on a single physical server and the communication is over fast Ethernet 100Mbp/s does this effects the performance i.e. speed since we are communicating simultaneously.
Thanks and Regards

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.
