Systemd Looking At A Future With More Varlink & Less D-Bus For IPC

[phuclv]

Why would one use json for a message bus payload and not something binary like - I don't know - messagepack? Serialising and deserialising json is not really efficient.
The following benchmark is using a very efficient json library. Note that the X axis is logarithmic:

actually json can be quite efficient: simdjson : Parsing gigabytes of JSON per second
although obviously it won't be as efficient as binary. Personally I would also choose binary over a text format like that. But designing a generic serialization format that's SIMD friendly might not be easy

Yeah, but simdjson will only help if you've huge messages. That's unlikely in this situation. I'd rather expect many small messages.

You must not have watched the presentation, because this garbage you let out is nonsense.

oh? what about what i said is untrue? in what world is ever using --> JavaScript <-- Object Notation acceptable for pid 0
