As Emacs-unicode has to map every character in a legacy
charset to Unicode, it's inevitable that such kind of code
version gets slower. For instance, on reading iso-8859-2
file, Emacs 21 only have to add some leading byte to each
character. But emacs-unicode has to lookup a table to get a
Unicode character code, and then has to get an UTF-8
byte-sequence for that character code.

Do you remember the name of fonts that emacs-unicode failed
to find?

I'm now synchronizing emacs-unicode to trunk version
gradually. But, it will take more days to finish
synchronizing.
