I've got a bunch of ideas, but it's hard to say. The code for this is
really simple:
https://github.com/systemd/systemd/blob/b0fc0763d38a0ad227c0f1d31662449696b13cf0/src/login/logind-user.c
You can try turning on debugging (add systemd.log_level=debug to the
kernel line) and then checking /var/log/daemon.log or whatever systemd
is logging to on your system (or journalctl). That will at least tell
you at approximately what times during the process things are slowing
down.
But just off the top of my head, I'd check nsswitch, name resolution, or
something else slowing down the process of identifying the proper user
until it times out. [You're probably in the best position to know if you
have anything like that installed.]
