FWIW here are some figures I just got copy a large file across my
network to my Pi 'NAS':-

chris@esprimo$ scp 2020-08-20-raspios-buster-armhf-lite.zip
backup:/bak/esprimo/cur/home/chris
2020-08-20-raspios-buster-armhf-lite.zip                          100%  434MB 
11.2MB/s   00:38
chris@esprimo$ scp 2020-08-20-raspios-buster-armhf-lite.zip backup:
2020-08-20-raspios-buster-armhf-lite.zip                          100%  434MB

As you can see I was using scp, the first copy is to an external USB3 hard
drive,
the second is to the Pi's SD card.  As you can see the speed is identical which
suggests to me that it's limited almost entirely by the network rather than the
Pi's internals.

It's all Gigabit (I checked), out of 'esprimo' which is a desktop machine, via
a
switch near my desktop, along buried UTP to another switch in the garage and
thence to the Pi.
