I can confirm that this problem still exists in Emacs 24:

[larsi@stories ~]$ time emacs -Q --eval '(progn (load-library "cl") (push 
"/usr/share/emacs23/site-lisp/anthy" load-path) (load-library "anthy") (load 
"/tmp/anthy-el-my.el") (kill-emacs))' 

real    0m8.037s
user    0m0.362s
sys     0m0.051s

However, is this a problem with the third-party anthy library, or in
Emacs?
