Not configuring with font-backend seems to make GNU Emacs behave as  
fast as usual. Many open boxes appear, the size of the glyphs found  
varies since different fonts are used. Now U+1F48 is taken from      - 
MUTT-ClearlyU-Medium-R-Normal--17-120-100-100-P-123-ISO10646-1  
(#x1F48). C-u C-x = still reports:

        preferred charset: gb18030 (GB18030)

or, complete:

                character: Ὀ (8008, #o17510, #x1f48)
        preferred charset: gb18030 (GB18030)
               code point: 0x81369132
                   syntax: w    which means: word
                 category: g:Greek
              buffer code: #xE1 #xBD #x88
                file code: #xE1 #xBD #x88 (encoded by coding system utf-8-unix)
                  display: by this font (glyph code)

It's definitely the enabled font-backend that consumes so much CPU  
power. With this enabled the HELLO looks a bit alien (left with font- 
backend, in the middle GNU Emacs 23.0.60 from ten days ago, right  
Emacs.app, the Cocoa variant):

And here is the start when the glyphs are not lined up correctly and  
do not seem to be the right ones (left window is from UnicodeChecker  
application):

The character info returned looks also strange. Finally a bit ps output:

  UID   PID  PPID CPU PRI NI      VSZ    RSS WCHAN  STAT  TT

The GNU Emacs with PID 839 is running since a few days, the other  
since a few minutes ...
