On this desktop system /home is mounted from an NFS server.  This was
usable in bookworm.  After upgrading to trixie, the shell doesn't
appear for several minutes, and then takes over a minute to respond to
some buttons.

The journal showed a number of services timing out (see the bottom of
this message).  After much experimentation I found that masking
localsearch-3.service makes this less bad, but it is still
unacceptably slow to start.

I created a fresh account to test this in isolation from any special
configuration I have that might make this worse, and recorded the
following timings (approximate, in seconds):

                        With           Without
		        localsearch-3  localsearch-3
----------------------------------------------------
Time to fully appear    ~120-500       ~90
Time to respond to          ~200       ~20
 "all apps" button
Time to respond to           ~60       ~60
 quick settings button

The response times are for use of the respective buttons immediately
after the shell appears.  When they are pressed a second time, or a
few minutes after the shell appears, the response is quick (< 1 s).

Ben.

that various services' startups are timing out seems like it indicates
some lower-level problem. I suspect that gnome-shell functionality is
blocking on those services' startups, which would happen promptly under
normal circumstances.

One good place to start would be to create a similar fresh account with
an on-disk $HOME (but otherwise the same system-level configuration),
and see whether that is equally slow to start. If this is a fully
diskless system, it could be on tmpfs if necessary; or if it has a real
SSD/HDD, use that (perhaps below /var/local).

Assuming the on-disk or tmpfs $HOME is OK, the next step would be to
narrow down which part of the home directory causes trouble when located
on NFS, by making a hybrid home directory where the top-level directory
is on one storage type but ~/.cache, ~/.config and ~/.local are on the
other.

My first suspicion would be dconf (~/.cache/dconf, ~/.config/dconf)
which uses a format that is designed to be mmap'd; but perhaps that's a
red herring.

Since you've said that everything is much slower with localsearch-3
(formerly Tracker), please try without that - I suspect that it might
just be another victim of the same underlying issue, but I'm also
quite confident that localsearch/Tracker was not designed with a
high-latency $HOME in mind.

This takes a while to start, most likely because it is waiting for the
portal backend x-d-p-gtk to initialize (the other major portal backend,
x-d-p-gnome, seems healthy). I suspect this might be either the root
cause, or at least several steps closer to the root cause than
gnome-shell is. Each of several IPC calls to x-d-p-gtk triggers another
attempt to start x-d-p-gtk, none of which is any more successful than
the first.
...
from the package of the same name, is taking a very long time to start.

Please try re-running it in the session, with verbose log messages
(/usr/libexec/xdg-desktop-portal-gtk -vr), perhaps using strace or
dbus-monitor to see what it's doing and where it gets stuck.

If it starts promptly when restarted within the session itself, you
could try using an edited version of
/usr/lib/systemd/user/xdg-desktop-portal-gtk.service and saving it in
~/.config/systemd/user/ - in this case you would only want the -v option
(not -r), and it might also be useful to set
Environment=G_MESSAGES_DEBUG=all.

This is clearly also getting stuck somewhere. As well as dconf, it makes
me wonder about perhaps GStreamer or Pipewire.

This, too, makes me wonder about GStreamer.
