Poor Throughput at 1KM

Please I need help on this as i cant just understand. I have a point to point link with the details below, but i cant get traffic of more that 15Mbps total. 99.99% of the traffic is UDP. I badly need it to get to at least 75Mbps of UDP traffic. The radio link is very good and i get under 1ms ping the remote site. The specs are

Each site has the same config
Gigapro board with VIA C3 2Ghz processor
256MB RAM
Mikrotik 2.8.23 OS
Routerboard11 minipici to pci adpater
Mikrotik 5G/ABP minipci card
5Ghz turbo band
5210 frequency
Ap-bridge mode
WDS enabled
All data and supported rates checked
Nsteme NOT enabled

Please advice urgently, like i said i need 75Mbps of UDP traffic, what can I do.

Thanks

Try without wds, and put card in bridge mode instead of ap-bridge.
Also play with frequencies.
You will be supprised how speeds can change by changing the frequencies.

Cheers…
