pfSense

Example:
LAN interface -> create 2 direct children qLink for the local traffic then qInternet that will house more children for External internet only
Under qInternet create more queues, qDNS, qLow, qHigh, qVoIP, qACK for example

under qInternet set bandwidth to 150 Mbit/s do not check borrow from other queues as i am setting max download bandwidth for all external services

each queue qDNS, qLow, etc is set to a % of bandwidth and all the queues are set to "borrow from other queues"

Now when i do a speed test with nothing else running on the network i should get max or close to 150 Mbit/s but instead get average 77.7 Mbit/s
