So, it was weird. I connected my laptop to the ethernet and............
BOTH Pi 3 and Pi 4 OMV NAS setups STILL are only getting around 10Mb/s
transfer
rates!?
So I don't know where my bottleneck is, but... with MY system currently
theres
no reason to run the Pi 4 with gigabit - I wonder where MY bottleneck is
at.
Test the interfaces, i.e. the NICs on each system and check that they
are *actually* running at 1000Mb/s.
There's a handy little utility called ethtool which can do this for
you or you can find the details for each interface in /sys/class/net.
Check also that network switches and the router can all run at 1 Gbps. And
that the NICs on both computers (Pi and the other end) can run at this
speed.
I spent a little while trying to work out why a SAMBA share between a
Windows and Ubuntu computer never got above 100 Mbps - and then I spotted
that the Ubuntu PC's NIC was only 100 Mbps and not 1 Gbps.
My Pi3 to my Windows PC (reading/writing to SAMBA share on Pi), with 1 Gbps switches, router and NICs, transfers at about 130 Mbps - for a large 1 GB
file.
My Pi4 to Windows achieves about 500 Mbps (peak) / 180 average for
Windows and a very steady 200 Mbps for Windows->Pi, in both cases with transfer initiated from Windows.
Those speeds are estimated from the Task Manager | Networking app on
Windows. In all cases the copies are from a USB-connected hard drive on the
Pi to a SATA-connected hard drive on Windows.
