Note that using converters like USB 3.0 -> Ethernet may introduce some overhead

Might want to try using a newer machine with Gigabit Ethernet built-in

There might be a CPU bottleneck too -
JohnLai may be able to explain this

CPU bottleneck, referring to meltdown and spectre vulnerabilities yes?
I ran the
tool to check and it showed performance is 'Good'
yeah probably the converter giving some overhead

cannavaroAccording to the spec "Up to 500Mb/s WAN Throughput"

https://www.draytek.co.uk/products/legacy/vigor-2130n that is probably the newer batches
the ones I bought were advertised as "up to 800Mbps"

Looks like router limitation. See here. Max routing speed is around 700Mbps.
https://www.smallnetbuilder.com/wireless/wi...howall=&start=3The USB3-Gigabit adaptor should be OK, maybe a little bit of effect on speed. I'm using the cheapest one I found on Shopee with my MacBook Pro.
Speeds I can get are:
mbpr:~ $ iperf3 -c 10.0.1.80 -R -i 4 -t 30

Reverse mode, remote host 10.0.1.80 is sending

Oh I see.. the speed sounds about right, similar to the test on smallnetbuilder
BTW how cheap is your USB3-gigabit adaptor?
