Hey Eric,
Thanks for reaching out to us!
This is the first report I’ve seen about slow performance with the 4.0.4 update and I personally haven’t noticed any issues when running tests today. That isn’t to say there aren’t other reports that we’ll see as we continue to get caught up on threads from the break.
To help us in trying to recreate things and see what the slow down could be, would you mind providing the system diagnostic information from the “Help” tab within your event settings? Additionally, if you’re able to provide a database dump that would help as well.
Thanks!
