The biggest improvement brought by the Untangle NG Firewall 13.0 release is to the poor latency generated by excess buffering in networking equipment, called bufferbloat, by supporting a queueing algorithm designed to optimize QoS and bandwidth to enforce a controlled delay. There are many innovative features implemented in Untangle NG Firewall 13.0, including Tags and Triggers, which promise to speed up enforcement and configuration. While tagging lets sysadmins tag a host, user or device to quickly create policies, triggers allow them to tag same things when a specific event occurs.
