Tune the query, tune the indexes. Without more information that's about all that can be said.

Also, if you have an inline table switch to a temp table so that you can get a true execution plan...gila is right, unless you provide more information there's not much to add...

No problems with inline tables (derived tables) and execution plans.

Check the execution plan and see if it needs any index or maintenance.
