Thank you Joe for leading me in the right
direction. I found the solution to the problem. It wasn't a hardware
related problem or an OLE DB driver problem...
By default, Windows XP installs the QoS Packet
Scheduler service. It is not installed by default on Windows 2000.
After I installed QoS Packet Scheduler on the Windows 2000 machine, the latency
problem vanished.
I am a happy PostgreSQL user now :)

Subject: Re: Windows 2000
Slower Than Windows XP
Sounds like it could be a networking issue to me. Perhaps
the xp machine is resolving the db server name more efficiently. do both
the xp machine and the win2k machine 1 have comparable network cards? 2
on the same subnet as each other and the db? 3 using the same dns or wins
server?
you could try putting an entry in the hosts file on the slow
machine to resolve the name of the db machine and see if that
helps.
I'm no expert on Postgre SQL so maybe there is a driver
difference or something that others on the list would know
better.
Hope that helps,
Joe
