Hi, we're writing a bulleting board using sqlalchemy at the moment, but we have the problem, that the database query for viewing a topic is quite slow for big topics. These are the relevant table definitions and mappings: http://paste.pocoo.org/show/62703/ This is the query that is slow: http://paste.pocoo.org/show/62706/ This is what EXPLAIN says: http://paste.pocoo.org/show/62708/ Executing this query needs up to 25 seconds on our test server that's just idling. On our productive servers (which aren't idling, of course) phpbb is able to execute an adequate query much faster. May you can help us speeding up this query? I don't know what to improve, since all parts of the query already use a key (except the derived one), but unfortunately I have a quite small knowledge of improving database queries.
