AWR1642BOOST: When parsing azimuth heat map, would using DCA1000 EVM enhance frame rate?

Hi 

I am trying to parse user data with heat map data.

But when using demo visualizer, it requires to drop frame rate below 5 fps.

Is it the limitation of AWR1642's computing power or limitation of speed of UART?

If it is because of UART communication, would it be solved by using ethernet communication with DCA1000EVM?

Thanks a lot
