rather offtopic for this list. but...
XML is about the most inefficient format imaginable, typically exploding
your data to many times its original size, especially if it has lots of
small fields
what format is the data in now that you're exchanging? I'd want to use
something close to the native format of the data. if performance is
important, you'll want to transmit the data in binary as close to its
native format as possible. if its complex structured data such as is
often expressed in XML, you could look at defining a binary interchange
format with JSON or ASN.1, but I'd be more inclined to roll my own
simple binary message format since its just between your own two programs.
