Slow updating at CHM (Chicago)?

Content

Is it just us or is Pod CHM just slow on processing updates?

We use Groups to determine who can see what part of our Home page; the options are the Home page section or the section that uses the Dynamic Object "Change Current User Details".  If they answer "Yes" to one specific item in that DO, they are added to the Group that shows the Home page section and they are free to roam in the system.

Normally it would take about 4 minutes for a "Yes" answer to be processed to that Group. While this seems too long, it has been consistent for more than a year. However, the last few days it has taken hours before that update has occurred.
