Hi, sorry to resurrect and old post, I just wanted to add that there is an option in UTM Essential firewall in Interfaces & Routing > Quality of Service (QoS): Here you can shape the bandwidth. I made some tests in the past, then I forgot about it, after some months I realized my upload bandwith was struggling. This could be of use fore someone else looking for help.
