Hi Mike, appologies I don't think I wa clear in my original post. I did not check the transmission time from the Arduino to the computer. I timed how long the actual Serial.write() function took to execute on the board itself, at 115200 I was getting ~600microseconds at double the baud rate I was getting ~300 microseconds.
AFAIK, the AVR should transmit to the Serial-USB bridge at a constant rate and that should be handled by a hardware UART
