We have noticed that the implementation of PrintWriter is very expensive
on Linux because of the underlying Unicode translations. I think that
the Unicode byte translations are probably just much better implemented
on Solaris. Use profiling to see where the code is spending its time.
It seems that much of our time spent was in JServ's
PrintWriter.write(). PrintWriter by nature is a text output writer so
it translates from Unicode to a byte output stream. That translation
is the expensive part.
