I noticed a serious problem with small packets UDP on Intel Atom mainboard (NIC Realtek).
I did a test environment. Intel D525 (NIC Realtek) server connected to Supermicro (NIC Intel). When I turn on Banwidthtest UDP local & Remtoe UDP Tx size = 150 is a server frozen.
I present images of frozen Intel D525.
It happens every time after a few seconds!
I think that this is also associated with the problems reported to the Board of x86. For example: http://forum.mikrotik.com/t/ros-5-10-5-12-very-unstable-as-pptp-bras-on-an-x86/53779/1
