What backhauls? How many sessions on the BW test? TCP or UDP?

Was wondering what peoples thoughts are on this Here is how things are setup. Every tower has a Mikrotik router on it. And is OSPF Routed. Route to the customer is (Tower A>Tower B>Tower C>Tower D>Customer) Tower A is where we have fiber, And our colo for the purpose of this issue. Tower A and Tower B connect via Licenced Backhaul and will do 200+Mb/s Full Duplex. Tower B and Tower C connect via Licenced Backhaul and will do 200+Mb/s Full Duplex. Tower C and Tower D connect via un-licenced Backhaul and will do about 80Mb/s. Customer Connects to Tower D. AP is a 5ghz Rocket with a sector. SU is a Power Bridge. Now, Here is the bandwidth tests. Using the Mikrotik Bandwidth test to get these results. Testing over each Backhaul from each tower will always max out whatever backhaul I'm testing. IE. Tower A>Tower B will do ~250Mb/s B>C ~250Mb/s C>D ~80Mb/s Then Testing End to End Tower A>Tower D ~80Mb/s (Maxes out the weakest link, The BH between C and D. This is expected) Now, The Strange Part. Testing from the customers Mikrotik Router on site. Testing from Customer>Tower D I get about 45Mb/s Down, And 30Mb/s Up. Testing from Customer>Tower C I get about 45Mb/s Down, And 30Mb/s Up Testing from Customer>Tower B I get about 15Mb/s Down and 30Mb/s up. Testing End to End Customer to Tower A I get about 15Mb/s Down And 30Mb/s Up. I don't get what is causing the customer location to show such slow speeds. I've tested multiple times, And Confirmed tons of free bandwidth on every Backhaul in the path. And testing Tower to Tower shows great speeds. We have the same problem in a few places. And in each case, We see a drop in speed as soon as it hits one of the licenced Backhauls. However, Each one of these backhauls regularly carries over 100Mb/s and have been tested to over 200Mb/s each time. Anyone have any ideas?
