You could use the Gnus registry if it's loaded.  It will tell you the
last place a message ID was seen (it learns this by looking at the
visible messages every time you enter a group, and by hooking into
spool/move/copy/delete on each backend).  It may not know the location
for various reasons, e.g. the user limits the size of the registry or
the message hasn't been seen yet, but when the location is available
it's a very quick lookup in a hashtable, probably much faster than
calling mairix to do a search.

The registry doesn't currently record the article number, but it could.
Currently a group name is always a string and anything not a string is
extra (non-location) data, so this is not a trivial change.  Since
article numbers are stable in some backends and not in others, this may
be quite a bit of work to do properly.
