Hi Paul,

The extra 'smart' calling takes 3-5 seconds for one search,
but it will not do that for most packages, it goes into
self._search_pkg_name_in_feeds first, if not found and then in to
self._search_pkg_provider_in_smart, only if we have such as python3
in the build session, it will take extra 3-5 seconds.
