  • A better (and easier!) idea might be to compare the execution plans for the two queries.

    You can compare the exec plans, but do note that lower cost does not always mean faster query, the costs are estimates created at compile time.

  • If you're comparing queries i'd be inclined to check i/o too...

    SET STATISTICS IO ON
