I'm developing a system in which we uses PI. We are facing a problem in which it takes 3 to 4 seconds from the time a PI tag is updated on the PI System Explorer, till the time Event Pipe count is incremented. PI event pipe count doesn't affect because our program checks it every 50 milliseconds. I would like to know if there are any performance related settings on the PI system that can be tuned to improve performance. Attached is images.
