I've always used MySQL with phpBB. I love MySQL. It's the database type I learned first, it's fast, the one I know better, and the one available on every server.
I think this also applies to ¿90%? of phpBB forums out there.
But lately I've been wondering if there would be a real advantage in learning and using another database type with phpBB, so I decided to ask here.
For example: Would I increase forum performance by using SQLite? Would searches be more accurate with a different database engine?
I googled a little bit, but didn't find any phpbb-focused comparison, so any experiences would be helpful.
