Yep I'm losing out here on around 10 Mbps (+/-)
Now the fun begins
It's now with Unifi Level 2 techs and I have a thread here
https://community.ubnt.com/t5/UniFi...Gateway-3P-Version-4-4-36/m-p/2689730#M135056
I had this response from Level2 Tech
“Please note that ~10 Mbps is an expected drop in performance due to NAT and Firewall especially in enterprise routers.”
I call “bullmuck”!

Looking at your stats on the UBNT forums, It shows that you are on a 3db line which also means you will be Re-transmit high. This takes the throughput percentage from 96% down to around 91-92%.
With Retx high on you will be looking at a throughput of around 66.5Mbps
You'll need to limit your line rate to reduce errors on it for DLM to remove the RETx high. I limited my line to 50Mbps and DLM put me back on Retx low after 3 days.
