How many rules do you have - and does it work OK?
I currently have 26 rules and I think that it takes ages to sync a new rule to the controller. If I understand this right, all the existing rules are built again when I add a new one. I wonder what takes so long, is it building the rules (on server) or getting the connection to the controller...
How many rules do you have?
Do you notice more lag/delay of execution with more rules?
