On the client side, you can use the ODBC data source configuration tool, in
the control panel, to turn trace on.  The resulting log file often provides
an indication of poorly structured SQL calls.  It's possible that the Client
Access ODBC driver isn't handling poorly structured calls as well as the SQL
Server driver.

Remember, the trick with ODBC is to reduce the number of interactions with
the server by means of optimized calls.  Often the server performs well, but
is doing a lot of unnecessary work.

The Client Access Express for Windows ODBC User's Guide offers a number of
performance tips.

On the other hand, if you'd be interested in effective tools for deploying
high-performance, interactive Web applications on your AS/400, I'd encourage
you to contact me privately.
