If you are getting lower than expected performance on Ubiquiti equipment, especially with Aquiss higher speed Pure Fibre FTTP services, this can be because you have some historical management in place.Step 1 - Smart Queues
Go to Internet -> Advanced Settings
and look for the option listed as "Smart Queues"
. Make sure this is turned off.
Step 2 - Hardware Offloading
See the article on the Ubiquiti site here https://help.ui.com/hc/en-us/articles/115006567467-EdgeRouter-Hardware-Offloading
There is a code snippet down the page that states
set system offload hwnat enable
set system offload ipsec enable
commit ; save
Once applied (and rebooted), you should see improved performance.
