Darren,

If the same sql is 10 times faster in the command window than from inside your app then we have to ask what is different between the two environments. Check on available memory, set command settings (especially set compatible which can cause all kinds of wierd stuff). Under most conditions a fully optimized query will take time relative to the number of records in the result set, that is the more records returned the longer the query takes to run. Can you post the query that is giving you these results?
