From our performance measurement, data size is the bottle neck for performance
in database application as majority of operation is to insert, update, and
retrieve
data. If most of your information in your database is English and W. European
characters, it is better to use UTF-8 as database encoding as it will take less
space than UCS2/UTF-16, which will give your better performance.

Jianping.
