We have used both Intel NUC5i5RYH

http://www.intel.com/content/www/us/en/nuc/nuc-kit-nuc5i5ryh.html

and the Intel NUC5i7RYH

http://www.intel.com/content/www/us/en/nuc/nuc-kit-nuc5i7ryh.html

We use Samsung 850 Pro SSDs and 16GB of DDR3L 1600MHz PC3 12800 RAM.

With the 5th gen, i5-5250U processor we did local iPerf tests with the
on-board NIC and against another box that had a 10G NIC.

owping statistics between the two boxes looked like this:

--- owping statistics from [ps-test-02.nsrc.org]:8763 to
[perfsonar.nsrc.org]:9800 ---

one-way delay min/median/max = -20.3/-20/-19.4 ms, (err=16.8 ms)
one-way jitter = 0.5 ms (P95-P50)
Hops = 1 (consistently)
no reordering

These were pretty typical test results fir bwctl (using iperf):

bwctl -c perfsonar.nsrc.org -t 30 -f m -i 1
bwctl: Using tool: iperf
bwctl: 36 seconds until test results available

We saw slightly better results when we connected 2 x NUCs back-to-back,
but I don't have those tests.

Bottom line - the 5th gen, i5, dual core model appears to sustain
1Gbits/sec throughput levels using iperf.

I have not tested the less expensive 5th gen, i3 models. We have not
tested the i7 NUC we have yet. I'm assuming it would be as good, or
better, but that just an assumption.
