Is there a limit of sites that can be configured in enterprise mode site list? How big site list will affect browser performance? We now have about 250 sites in site list and started wandering how big it can be. Couldn't find any documentation about that. Current domain policy is to open all intranet sites in IE mode and we are adding exceptions (i.e. urls to open in chromium tabs) to site list. At some point we will need to do opposite: to create site list only for resources that need to open in IE mode. But how big site list we can make?
