Confirm that catalog compression is working

Hello,

Is there a way to confirm that catalog compression is working?

We are using lots of disk space and I was looking at the image cleanup job and it is reporting that it is finding >8000 records to compress each time it runs (every 12 hours).

Here is a sample job:

04/29/2014 04:45:53 - Info bpdbm (pid=12659) image catalog cleanup
04/29/2014 04:45:53 - Info bpdbm (pid=12659) Cleaning up tables in the relational database
04/29/2014 04:45:53 - Info bpdbm (pid=12659) deleting images which expire before Tue Apr 29 04:45:53 2014 (1398771953)
04/29/2014 04:51:32 - Info bpdbm (pid=12659) deleted 37 expired records, compressed 8380, tir removed 0, deleted 37 expired copies
