Thanks for your reply and suggestion.
I have tried as your suggestion to test IPQ8064+QCA9880 with Ath10k CT
firmware/driver to run throughput UDP/TCP. Unfortunately, I could not be
able to see throughput improvement. Could you please suggest what may cause

We have not done a lot of testing in AP mode, but when using 9880 3x3 compex
in our 2U rackmounts (high end Intel E5 processors), and with CT
we see near 950Mbps UDP download in station mode. I think we were a bit
AP mode, but not that much.
Are you testing TCP or UDP traffic?
Have you tried normal STA/AP mode instead of WDS?
Maybe you are CPU bound on your platform?
