Do "query occupancy KUJIRA" and add the file counts.
A select statement will work:
   select sum(num_files) from occupancy where node_name='KUJIRA'

I get about 100,000 files/hour deleted on my server. (aix 4.2.1 adsm 3.1.2.42)

The files are just deleted in the database, the tapes are not touched until 
they are targets for reclamation.
