Kevin Hill has a public service announcement:
I’ve been hearing throughout my entire DBA career that 300 seconds is a good counter for PLE (Page Life Expectancy) to be above.
Paul Randal calls this “utter nonsense“. If anyone would have the right to say that, its Paul.
It is good for the number to be above 300, but that’s like saying it’s good to have your brand new car last a year and a half.
