I don't use emacs-rails, so I cannot really test.

Which version of Tramp do you use? Note that Tramp 2.1 performs much
better than Tramp 2.0.

If it is Tramp which performs bad, you might check its traces. Time
consuming operations are commands sent on the wire. Set tramp-verbose
to a suitable level. Maybe you can also provide us the traces if you
don't see useful information there.
