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)
	     -MUTT-ClearlyU-Medium-R-Normal--17-120-100-100-P-123-ISO10646-1  
(#x1F48)

	Character code properties are not shown: customize what to show

	There are text properties here:
	  auto-composed        t

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        
TIME COMMAND
   501   839   816   0  31  0   113432  43980 -      S     ??

1:25.70 src/emacs -Q

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

Behold the warranty ... the bold print giveth and the fine print
