Hi!
I have fanless pc like this. It has two identical realtek ethernet NICs, re0 - external, re1 - internal.
Network speed on re0 seems normal, and files downloaded from internet with speed, which provider declare (7-8 megabyes per second).
But speed on internal realtek device is about 1 megabyte per second, which is really slow.
I do not configure any shaper or complicated firewall rules. Load averages when I load file 0.25, 0.21, 0.11 (or less), so CPU not overloaded.
I simple copy file via sshfs to/from my linux pc.
If I use instead this FreeBSD-minipc router DIR-615, using network cable I can download files from internet with speed 7-8 megabytes per second, so problem not in my linux pc.
I'm trying also insert switch between linux pc and freebsd pc, but no changes.
How check why speed is lower than it must be?
