I'm not an SQL DBA by any serious standard but I am trying to figure out why the logical reads have gone bonkers on a DB I have for a line of business app. the image below shows a 10 x increase in logical reads? what could be causing that? Feel free to ask for any other info, as far as I can tell server performance metrics are fine CPU/Ram etc The area highlighted in green is where I would like to get back to, as you can see the execution count has not really changed :-/
