Unfortunately I've no time to investigate further now. Perhaps in 2-3 weeks.

But it should be really easy to test this issue:

First you try this command with a geometry, that lets Emacs fill the
whole screen:

time emacs -g 500x200 -Q --eval "(progn (require 'notifications)
     (dotimes (i 20) (notifications-notify :title \"TEST\")) (kill-emacs))"

And then the same with a small Emacs frame like "-g 10x10".

With my installed version 27.2 the first example takes 9 seconds. The
latter less than 1 second.

My notification daemon is "mate-notification-daemon".
