Like specific binary formats, specific serialization code can be
significantly faster. I did a test like this once in the context
of an RPC-ish infrastructure.

JAVA serialization was *much* slower than XML, but XML was *much*
slower than binary (*much* >= 2x). This was especially noticeable
for smaller units of data where Java reflection and TCP/IP packet 
latency become performance bottlenecks.

I think Rick also performed some analysis of this sort.
