Changed to: Remote database performance

I have had issues with getting decent response speeds from Windows
applications I have written using ADO.  I know it isn't the AS/400 "per se",
because the same query will run fast as hell if run with wrkqry.  It seems
the problem is when trying to use the AS/400 as strictly a database and
having thick clients access it for data.

Are you saying that is the wrong approach?  I should have the database on
it, build a server app on the AS/400 that does the actual querying and write
an interface for my desktop client to talk to the server to handle data
transmission and not rely on IBMs OLE DB drivers?

This performance problem I have is also oriented with Crystal Reports too.

I have a Linux/PHP webscript that runs 2 left joins and uses DB2 Connect to
access the AS/400 and performance is a lot better.
