This script displays your most resource-intensive queries from the plan cache,
and points to ways you can tune these queries to make them faster.


To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.

Known limitations of this version:
 - This query will not run on SQL Server 2005.
 - SQL Server 2008 and 2008R2 have a bug in trigger stats, so that output is
   excluded by default.
 - @IgnoreQueryHashes and @OnlyQueryHashes require a CSV list of hashes
   with no spaces between the hash values.
 - @OutputServerName is not functional yet.

Unknown limitations of this version:
 - May or may not be vulnerable to the wick effect.
