Both dbeaver, Firefox and the desktop in general suffered from latency (dbeaver was the most severe).

What about a single xterm? Is that fast?

You can disable the X server x2go is using (VcXsrv) from x2goclient's
menu. Then start mobaxterm and enable the X server there. I have no
Windows at hand to describe this more precisely, sorry.

The only thing I can think of is that your session might use 3d
rendering which is slow. Maybe you can run dbeaver with
-Dsun.java2d.xrender=True.
