    That is linked to the Tech Support case #781593 where a single PI Vision display consumed 70 times more SQL resources, frequently reaching at 100% CPU, than 20 other system databases with +500 active users. The PI Vision display was referencing data from multiple AF Elements with some of them having a tons of Event Frames. As a workaround, I disabled the EF Update and set the EF Update Rate to 30 mins (was 5 seconds) on the entire PI Vision system...
