IMO if you trying to get the maximum performance and minimum memory size requirements you have to
throw away any text-based formats and use only fine tuned binary data formats. Of course you need to
spend some time to write specific debugging tools and data viewers. But it will gain you a lot anyway.
In my embedded system practice when every byte and every clock cycle counts binary protocols beat
text-based every time.
