Well, if you switched from using SQLite to using SQLite3 then you would see 
exactly this kind of slow down.   I have found that SQLite3 is *much* slower 
because the default way it handles writing to the database is very different.  
Some of the speed reduction can be fixed by properly configuring is, which is 
done automatically in the database creation scripts, but during an upgrade, 
it is unlikely these changes to the default SQLite3 behavior would be made.

I think you have found the source of the problem.  You have several choices:
1. Switch to MySQL, which is much faster (possibly PostgreSQL, but it is 
slower than MySQL).
2. Keep using SQLite version 2
3. Take a look at the 1.38.11 make_sqlite3_tables scripts for the optimization 
modifications and apply them to your database.  It will still probably run 
much slower than SQLite version 2.
