>Pulling even the top 200 records can take 1-3 minutes. Very slow. We're trying to see what the delay is (it could be anything in the topology other than the driver). They don't have SQLServer on their system so we can't test pulling records from sqlserver as a comparison. In the past, adding an index tag in foxpro on the tables has improved performance, but we really don't know what may be the culprit here.

What is the size of the data your pulling down? Are you testing against a single or multiple tables and with no index?
