The archive metadata mirror currently needs about 500 MB of space (~15
MB per suite and architecture, or something like that).  The database
itself needs about 250 MB peak.  Updating it currently results in
signifcant CPU and I/O load.

I don't know enough about the load on gluck to tell whether this is a
problem or not.
