This script gives you a prioritized list of why your SQL Server is slow right now.

This is not an overall health check - for that, check out sp_Blitz.

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:
 - Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000. It
   may work just fine on 2005, and if it does, hug your parents. Just don''t
   file support issues if it breaks.
 - If a temp table called #CustomPerfmonCounters exists for any other session,
   but not our session, this stored proc will fail with an error saying the
   temp table #CustomPerfmonCounters does not exist.
 - @OutputServerName is not functional yet.
 - If @OutputDatabaseName, SchemaName, TableName, etc are quoted with brackets,
   the write to table may silently fail. Look, I never said I was good at this.

Unknown limitations of this version:
 - None. Like Zombo.com, the only limit is yourself.

Changes - for the full list of improvements and fixes in this version, see:
