Ran a quick benchmark with and without ping -f and 20x performance increase with ping vs. without (below); I'd like to see this bumped up to High since this poor performance is impacting testing using these boards. I also came across a similar problem on another board that may help with a fix (or not - https://lists.yoctoproject.org/pipermail/poky/2011-June/006649.html).
