Timo,
If I understand your system correctly I suggest you're missing out on
the full benefits of Guacamole.
My experience of VNC direct (which is what I take you to be doing) is
that it can be quite slow, especially with limited bandwidth. Given the
same bandwidth capacity I have found Guacamole to give a much improved
experience.
Depending upon other things the Pi's are doing I expect you should have
sufficient resource to run Guacamole on them. Out of interest I tried it
on a Pi3 and it was ok - not as good as on a later Intel box, but more
than adequate for 2G - a Pi 4 should be somewhat better.

I have tested guacamole little bit and it works better than teamviewer/anydesk
on those slow (sometime also unreliable) connections.
What I have tested these connections to remote devices, it somewhere 7-15kB/s
(60-120kbits) and latency 150-400ms.
My setup is following:
- on our office (fiber connection) I have installed guacamole and guacd on
virtual server
- from that virtual server there is OpenVPN tunnel to IoT Operator network
- remote device has 2G/LTE-M modem, Raspberry Pi 4 and two devices which only
offers VNC connection
- to connect those VNC device I have tested guacamole
Because we have some computing power left on those Raspberry Pi's I started to
think should I install guacd on Raspberry Pi? Or is it even smart move? Or are
any other optimization what I can do?
