Hello Flemming,

Thank you for making these tests, and posting these results. As in the case
of my APU2E4 tests, your's are also showing that the traffic saturates the
1G bandwidth, which is great. We can then recommend, in the doc., that the
Qotom PC family is a suitable and tested alternative for a home router.

The next step is waiting for you to get a 2.5G fiber :-), and find out if
the Qotom would saturate close to that bar. Of course I'm joking this time
:-) .

Thank's again

and cheers,

jrb.
