  #244707

  I have created these SPs as helpers for me when performance tuning/ measuring.

  Sample usage:

  EXEC helpers.dbo.StartPerfTrace;

  GO

  DECLARE @bb int;

  SELECT top 100000 @bb=ROW_NUMBER() OVER(ORDER BY @@SPID)

  FROM syscolumns,syscolumns a

  GO 10

  EXEC helpers.dbo.StopPerfTrace;

  Sample output:

  

  I find these very useful, but wondered if anyone had any good suggestions on other useful information I could include or just general critique of the techniques used.

  If you can find time to take a look and maybe have a play I would appreciate it, thanks 😀
