With fontconfig-debuginfo installed I get this:

     33.61%    emacs  libc-2.18.so                   [.] __strchr_sse2
     15.77%    emacs  libfontconfig.so.1.8.0         [.] 

OK. Next steps probably are:

1) Compile with '--with-x-toolkit=lucid --without-xft'
   and check how fast HELLO is displayed.

2) Identify all font packages installed. I don't know about SuSE,
   but on my Fedora system all font packages are under 'User Interface/X'
   group, so "rpm -q -g 'User Interface/X'" shows all font packages
   (plus other X stuff, which may be filtered out by grepping for "noarch"
    packages). On my system, the following command:

   rpm -q -g 'User Interface/X' | grep noarch | grep font | wc -l

   shows 84 font packages.

3) Save list of packages obtained at step 2) and try to uninstall the most
   of font packages (but do not touch X core fonts - xorg-x11-fonts-* packages
   on my system). Next try to run "regular" (with Xft support enabled) Emacs
   and check whether font removal helps to speedup C-h h.

4) Reinstall all required fonts.
