Even in a binary format, much processing is necessary - the format has
to be architecture-independent. So, whether you choose text or binary
format, you will have to "parse" the returns, and "format" the parameters.
Please, just try the text format for parameters and result. I could
measure no difference in performance (if anything, the text format was
fractionally faster)! The text format is much easier to get working and
more forgiving with respect to typing. Once your application is working,
then evaluate whether the text conversion is a problem.
