It depends on the use case. `find-grep-dired' is something I call
permanently, for example.

For a performance comparision, you could check the figures in
<http://cvs.savannah.gnu.org/viewvc/*checkout*/tramp/test/tramp-time.el?root=tramp>.

Tramp 2.0 has no cache, Tramp 2.1 does. The figures are some years old,
but they shall be still valid.
