One thing that often amazes me is that many SQL Server developers do not actually measure the performance of their queries. Many of them thought that you needed external tools, more or less complicated, to run against your server, and they did not have the time or inclination to learn and try these. This article will describe a couple of much easier methods of measuring performance of queries.
