The chunking bit of the protocol implementation could be sped up by not constantly checking if chunking is necessary but postponing the chunking until it's needed (i.e., before wrapping up a bolt message or when collecting the byte stream to send it over the wire). This change includes an extra copy of the data in memory, but since data is usually written in small amounts per buffer write and chunking occurs rarely compared to this, the cost of constant checking outweighs the cost of the extra copy for most practical use-cases.
