187 queries per second with 0 connections?? Gateway is pegging my CPU with nothing in the designer at all… Why is it? My database is not allowing me to change my scanclass speed… I think I have a throughput of 83 exe/sec with a 1ms delay and another with .1 exe/sec with 10 seconds delay. I am unclear on how to modify my scan class? There is little to no info available on scan classes or data sets and tags. I only need to make a simple log display for extremely rapid tag changes. ---

I am also losing my connection to my database randomly… SQLserver2008. Changing the speed of my scan class did nothing to help as I thought it might.
