Hah yeah @mix I have been watching that as well. We established that json parsing and stringifying is a big part of the performance problems we are seeing. I tested turbo-json and the 5x speedup is real. Also he optimizes for bytes that will fit perfectly with us. There are two problems right now with using it for messages: 1) We need anyOf otherwise our null or string for backlinks won't work and 2) we probably need something like an old school json.parse in the middle for the content part.
