title: Is there a SQL server performance counter for average execution time?
body: <p>I want to tune a production SQL server.  After making adjustments (such as changing the degree of parallelism) I want to know if it helped or hurt query execution times.</p>
  
  <p>This seems like an obvious performance counter, but for the last half hour I've been searching Google and the counter list in perfmon, and I have not been able to find a performance counter for SQL server to give me the average execution time for all queries hitting a server.  The SQL Server equivalent of the ASP.NET Request Execution Time.</p>
  
  <p>Does one exist that I'm missing?  Is there another effective way of monitoring the average query times for a server?</p>
