If you are on a slower link, you may want to tweak the speed and quality
settings to better suit your preferences: quality vs bandwidth vs
latency/framerate, choose one.
By default, Xpra is optimized for faster links because that's what most
users have - at least those that file tickets.

You may also want to file your own ticket if you find that specific and
reproducible bandwidth conditions trigger abnormally large lag.
Newer versions should improve this.
Please always specify which version you are using for testing, what
distribution, etc.

NX open-source has been abandoned a long time ago.

Yes, NX was quite efficient when applications were painting the screen
using X11 primitives, as it is compressing those requests. But very few
applications do that any more. It lacks all the progress made in video
compression that happened in the last ~10 years or so.

Very very unlikely.
