After multiple tests and tweaks i believe the issue is not with the HW or N=
uma related (Infinity fabric should do around 32GB) but rather with FreeBSD=
 TCP/IP stack. It's like it cant figure itself out properly for the speed t=
hat the HW can do, i keep getting widely varying results when testing. Belo=
w is an example of two tests, with about a 15 second break in between the t=
wo.
