emerge bwmon,

It measures across the ethernet ports, so adjust your test,
according to what you want to measure, crossing the ethernet
port on the target system.

Gigabit ethernet rarely runs full out constantly, something, (ram, cpu,
interface, swith-latency....) mucks things up. Do not let your "copper"
get to long either!

Some fraction say 50% is good, if it is copper, unless the systems
are smoking "gaming" systems or of very high quality resources.

emerge iotop (then rebuild kernel)

Rebuild your kernel to use "iotop" and see what happens. You may need
to tweak your kernel parameters to optimize IO operations.....
(just gessing here)....
