Line buffering means each line is transmitted as a separate network
packet. Normally, as much data as fits into MTU will be stuffed into a
single packet. That's why leafnode has to fflush() its output after
a reply is completed.

All commands that transmit large amounts of data may suffer from line
buffering because it increases overhead.

How much this slows down transmission depends on the type of network.
