17m	comment	Troubleshooting SOS_SCHEDULER_YIELD wait That would do it :-) Glad you got it figured out.
14h	comment	Troubleshooting SOS_SCHEDULER_YIELD wait You're saying you re-ran the same workload in off hours. Take a look at the CPU time demand for that workload. They may not necessarily be unrelated.
14h	revised	Troubleshooting SOS_SCHEDULER_YIELD wait edited title
14h	comment	Troubleshooting SOS_SCHEDULER_YIELD wait Also notice that your signal wait time seems to be a large portion of your wait time (it's inclusive in wait time), further indicating CPU pressure.
15h	comment	Troubleshooting SOS_SCHEDULER_YIELD wait Some things to check: See if other processes are consuming a significant amount of CPU time, check current waiting tasks with sys.dm_os_waiting_tasks and see what their wait types are. Look for heavy CPU consumers like a large number of compilations and recompilations. Check virtual file stats, blocking, and other generic troubleshooting. Look into the plan cache (or use an XE session) to get high CPU consuming queries, etc. Lots of troubleshooting, and SOS_SCHEDULER_YIELD isn't necessarily always accompanied with consistent non-zero value for runnable_tasks_count.

23h	comment	Is there a way to generate an execution plan for a stored procedure before executing it? msdn.microsoft.com/en-us/library/ms191194.aspx
1d	comment	Startup procedure for availability replica becoming primary Have these as job steps, use conditional logic to determine whether or not job step execution should continue.
1d	comment	One filegroup, multiple datafiles, how to get list of tables in each file Good point and agreed. Also, good answer, +1.
2d	revised	Startup procedure for availability replica becoming primary added 73 characters in body
2d	comment	One filegroup, multiple datafiles, how to get list of tables in each file There's no guarantee that tables will be spread equally across the files. I can think of a few situations where that isn't the case (index rebuild being one).

May 17	comment	Re enable Windows Authentication Reference: msdn.microsoft.com/en-us/library/dd207004.aspx/css
May 17	comment	Re enable Windows Authentication Ok. If you are a local administrator on the machine, start SQL Server in single user mode (-m) and connect to reset the `sa` password.
May 17	revised	Re enable Windows Authentication edited title
May 17	comment	Re enable Windows Authentication What do you mean, Windows Authentication was disabled? In SQL Server, you have two options for authentication: Windows Auth or Windows and SQL Auth.
