QCA9880 3x3 80Mhz low performance

[Phyu The]

Dear Ben,

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 
low throughput?

thanks,
Phyuthe

We have not done a lot of testing in AP mode, but when using 9880 3x3 compex 
NICs
in our 2U rackmounts (high end Intel E5 processors), and with CT 
firmware/drivers,
we see near 950Mbps UDP download in station mode.  I think we were a bit 
slower in
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?

Thanks,
Ben
