I've posted an issue on github (https://github.com/mc-server/MCServer/issues/1800 ) regarding more intelligent chunk update broadcasting.
It might also be possible to make use of the Multi Block Change packet rather than always sending an entire chunk. It is definitely possible to make better use of Primary Bit Mask in the chunk update packet, given that we store data in this format.
