Hi,
Just started looking why in lat few weeks my gnome desktop los a lot of its
previous speed. I found that already it is consequence of some issues in
last chrome. Seems chrome developers managed to kill few most annoying
memory leaks causing that time to time crome processes associated with some
tabs age exploding consuming +2GB memory.
Despite this I found some fact that I was not aware about GDM.
Theoretically GDM should provide just application running on top of raw
X11/Wayland diplay to provide authentication service.I remember that few
years ago it was really like this but seems not it is no longer so simple
picture.
Just simple ps output:

shows that gdm user is running whole set of processes running in full
separated X/Wayland session.
Is it really needs to be so complicated? Those processes are not all.
Because in this tree is running gsd-housekeeping definitely it will be time
to time much more like tracker processes (by the way there is no no
possibility to disable tracker in X/Wayland session).
I know that things are changing and many new features should be or could be
handled by Gnome desktop but seems somewhere in the past Gnome started
derailing from the KISS principle path.
Is it any existing alternative to start Gnome desktop not over GDM?
