what is the fastest (high speed data transfer) way of connecting the Arduino due board (running a high speed motor) with Simulink for realtime data transmission and control?

Hello,
I am using Arduino due to run two motors of high resolution encoder at high speed in simulink block diagram for feedback control and real time data transfer/feedback.
what is the fastest (high speed data transfer) way of connecting the Arduino due board (running a high speed motor) with Simulink for realtime data transmission and control?
Thank you :)

Ethernet.
These days the W5100 is not recommended, and people use W5500 based devices instead. At https://forum.wiznet.io/t/topic/7592 a developer of the W5500 says the maximum rate for that chip itself is 15 megabits per second; I have not checked to see how quickly you could actually transfer data with the Due. It appears to depend on the SPI clock, which https://forum.arduino.cc/t/spi-clock-in-arduino-due/518710 says defaults to 4 MHz
