I am also struggling with the speed issue. :) Rick is the expert and I am
also asking him on this problem.
For your problem, I suggest you to use a general test software like netperf
first. Then it can bypass the problem in your own test program.
In my system, the ping speed is also slow. From board to pc is 2.1ms and
from pc to board is 1.8ms.

This should not be a problem because the platform is so common.
