I've used SBE and Aeron, can recommend. The difference with SBE vs JSON is there's no need to serialize/deserialize anything. In SBE you literally just write in the value and read the value. You aren't turning bytes into text, which takes time and might require intermediate state (depends on what you're implementing). It's almost like a non-format, because what could be simpler?
