We don’t have any guide. These things are old and slow, so only create tags for the data you need at as slow a rate as you can tolerate. Some people used leased scan classes to speed things up when tags are visible on a screen but disable or slow them down otherwise.
Thank you very much for this advice. After deselecting the Comms Servicing Sel S:2/15 bit, the load factor for this processor changed from 440% to 31%. Also, the fastest update we could get on these tags was about 30 seconds, and now it is 5 seconds as it should be. This helps a lot!
