Is there anyone out there in the "using c4j for a while" category?

I'm using JDBMWordsDataSource (in the classifier4j-optional jar). It's not a
flat file, it's a non-relational database - see
<http://jdbm.sourceforge.net/>

It is much, much faster (at least 10 times from memory) than any JDBC based
database I've tried. However the current implementation doesn't support more
than one category.

I'm also using an old version of Classifier4J with HSQLDB for another
project.

I do (or did?) have some hard numbers somewhere. I'll try and find them for
you.
