I don't want to be nit-picky, but the default does whatever you set when adding
your repos. If autorefresh is on it is a performance penalty. That's why it is
not turned on by zypper by default.

We're already working on a query command, which will behave differently. No
refresh per default and no fancy output. Preferably supporting a custom output
format line rpm `--queryformat'.

Obvious overhead in that case is the launch of the rpmdb which transfers the
stored gpg-pubkeys into zypp's keyring. The `--no-refresh` does not need them
at all, and even the refresh case only if metadata need to be updated.
