What's the difference between these two implementation in node.js?

I'd like to know if there is a difference, performance wise between:

1) in the same port:

var http = require('http');

http.Server(function (req, res) {
  if (req.url == 'foo') { foo(); return;}
  if (req.url == 'bar') { bar(); }
}).listen(123);

2) splitted on 2 ports

var http = require('http');

http.Server(function (req, res) {
  foo();
}).listen(123);

http.Server(function (req, res) {
  bar();
}).listen(456);

3) in 2 separate js file that I would launch on 2 different node cmd.

foo() and bar() being functions that can take time to resolve like uploading files for example.

#1 and #2 will be basically identical in terms of performance. If you run two servers like in #3 and you have a multi-core machine you will be able to perform up to twice as many simultaneous requests, depending on the IO required and available.

Two different node instances give you two CPU threads (but use up more memory and cannot easily share state). That is the only real difference I can see.
