Loading cc-mode in Emacs 23 takes 0.33 seconds on my current laptop
(about 0.3 seconds for Emacs 22).

Apparently, the netbook you are using (Lemote Yeeloong) has a 600-800
MHz processor.  That shouldn't be so slow as to yield 20 second loading
times.  There's likely something strange going on.  Could you try with
Emacs 22 and see if the problem recurs there?
