Hi.

I run a Cnews machine with a few high-speed (NNTP) feeds.  My problem is that
two of them have excessive (> 80%) duplication.

Here is part of one days summary file:

-----------------------------------------------------------------------
NNTP reciept statistics: 4330 total articles.

I switched from dbz back to dbm because with dbz I was getting around 95%
duplication on *all* of my feeds, but I still have some problems on my
fast feeds.

Does anyone have any suggestions?  Thanks.
