Subject Re: Database DataStore vs File DataStore: Performance.

I didn't measured performance, but probably the file data store is a
little bit faster than the database data store. I think it's just a
matter of preference, I don't think one or the other is 'better'.

Some JDBC drivers try to load BLOBs completely in memory. If you have
large documents this can be a problem. If I was you, I would test with
a 200 MB document to make sure there are no surprises later on.
