Joe,

Is data conversion a java issue ?
As you are one of the super-defenders of the as400,
isn't the AS400 one of the few systems that can create unicode DB-files ?

Indeed data conversion does take extra cycles, 
as it does for p.e. date-fields 
(ever tried to convert a file with 10 date-fields to pure numeric data?
=> performance gain of a factor ... ),
but most people will use this date-fields in their system for 'ease of use'.

(PS: we don't, due to this performance degradation)

For real comparisons in your tests: 
do a read/update on a simple file in RPG.
then do the same on a 13488 CCSID file, also in RPG .
then ...

(of course, unicode files do need extra diskspace .)

The biggest issues with Java itself is the data conversion.
EBCDIC->ASCII, character to String ...
