My results are in stark contrast to yours:
. with the current emacs-25 branch, an unoptimized build:
$ ./emacs-bug22519.sh --fundamental no
mode: normal
latin-9=(5.0 5 0.10899999999999999)
utf-8=(10.14 13 0.44)
$ ./emacs-bug22519.sh --fundamental yes
mode: fundamental
latin-9=(0.359 0 0.0)
utf-8=(2.938 4 0.126)
. with Emacs 25.0.92 pretest, compiled with -Og:
$ ./emacs-bug22519.sh --fundamental no
mode: normal
latin-9=(0.64 5 0.046)
utf-8=(1.953 13 0.156)
$ ./emacs-bug22519.sh --fundamental yes
mode: fundamental
latin-9=(0.109 0 0.0)
utf-8=(0.984 4 0.062)
So while there is some slowdown when showing these symbols (which
could be due to the need to load the necessary font), the slowdown is
nowhere as dramatic as on your system.
IOW, I still cannot reproduce the problem on my system. I suspect
some issue with your font configuration, but that's just a guess.
