JSON can be parsed very quickly: https://github.com/simdjson/simdjson https://github.com/simdjson/simdjson CBOR could be another option: https://en.wikipedia.o

  JSON cannot be efficient for binary data or even utf8 strings because it needs escaping which means you can't have a zero-copy implementation. CBOR is better in that regard, yeah.

    All it needs to beat is stringifying and formatting that /proc|/sys already does

  It can't (simdjson is fast compared to other text parsing - it's still extremely slow compared to native types), but that fact actually doesn't matter because the problem isn't the parsing. Even the construction of these text files in proc is too slow. You can't read /proc/net/tcp within a reasonable amount of time on a system with hundreds of thousands of connections. Even allocating/churning memory to store a textual representation becomes a problematic overhead.
