A decently designed binary data encoding protocol will
take less space to encode and transmit, and less time
to decode, than a decently designed text based one.
Just think: writing an integer as four bytes takes
one instruction, maybe two if byteswapping is needed.
But writing "32768" takes more bytes, and more time
to encode/decode. Text compression costs even more.
There is no way to recover those differences.
Of course those "decently designed" binary protocols
rely on things like contextualized encodings. If you
demand self-descriptive data, then it's easy to get to
the point where manipulating type data costs so much
that encoding/decoding differences are in the noise.
And some programming environments basically don't
support binary data worth speaking of. So there are
going to be tradeoffs to consider.
