I have install SQLExpress2008 on a WS2003 with 2 Gb RAM (development machine)

When I run a query against a table with 100.000 records from the Microsoft SQl Server Managent studio:
[ Select top 1000 from sometable ]
It returns the results in less than a second.

But when I run the same query from VFP
[ sqlexec(nHandle, "Select top 1000 from sometable ", "cur") ]
It takes for ever, more than 15 seconds.
What is the problem ?
