Oracle Forms App very slow on some computers

[Ridolph]

We're running an Oracle Forms App called Pledgemaker (for non-profits).
It's running under Oracle 9.2 under Windows Server 2003. On half of our
clients (all well-equipped dells), it runs fine, but on the other half
it is extraordinarily slow. I'm looking for clues as to why this is.
Everyone is configured in about the same way. The app is running off of
the server. The server is not overloaded.

I was wondering if anyone had run into anything similar with an Oracle
Forms application under NT, or if there might be some other explanation
for the problem, like network trouble (though nothing else has
problems). I'm used to Oracle under Unix, not NT, so any suggestions
about how to diagnose this would be helpful.

Thanks!

We once had a similar problem here and the cause was that some network
cards had configurations not compatible with the switch, it was not
recognizing flow control, auto speed, etc. It seems strange but after
fixing the configurations, performance improved a lot.
