Here is the question: Should I store XML files in a database, or

The file system would be faster, since SQLite sits on top of it,
anyway, so you have its overhead no matter what.
Regards,
I'm making something that requires XML. (ooh, secretness)
It would also be nice to use SQLite with it, but I am confused about
how much things I need to put into the database and how much that
needs to stay on the file system.
You probably didn't understand that. My describing skills suck.

I seem to recall that there was a significant performance difference
between using sqlite3_exec vs prepared statements. You might try
using sqlite3_prepare/bind/finalize.
I would add that you need to do all of your database retreiving before
starting the updating.

I'm already doing that (unless I'm doing it wrong?):
nRet = sqlite3_exec( m_pDB, _T("BEGIN;"), 0, 0, );
...
nRet = sqlite3_exec( m_pDB, _T("COMMIT;"), 0, 0, );
