Hmm... is other timing information available? In reality (in our
case) UTF-8 is not competing against UCS-2, but against EUC and
ISO8859. Based on what you are telling me, I assume it's probably
20-30% slower than ISO8859 also, but how about EUC?

It seems to me that UTF-8 should not be very different from
EUC in performance (since both are multibyte encoding). Or
am I missing something?
