I want to run sp_Blitz and other scripts (from first aid) on a busy primary production server.
There are 75 databases on the server, of which 40 are in an availability group (synchronous, no read scale).
I am reading the readme file which says
@BringThePain = 1 - required if you want to run @CheckUserDatabaseObjects = 1 with over 50 databases. It's gonna be slow.
The term pain is scary and so I want to ask whether the pain is in terms of the time that I have to wait to get the response from the stored proc or does pain mean that its going to cause blocking/slow production workload on the sql server?
