1) turn off all ODBC query logging from both the ODBC driver and the
ODBC administrator. This feature is a performance killer. Only use
this feature if you are trying to debug a problem.
2) Some client programs try to perform the joins on the client side
rather than the server side. I would check if the client is actually
passing the actual SQL statement back to the server. If it is trying
to perform the join on the client, it could be a big performance
killer.
