Comment (by yurivict271):

 The valid way to compare compression methods for a particular purpose is
 to take your data samples and run it through lzbench
 (https://github.com/inikep/lzbench).

 Compression method should be a function of the current network speed. When
 the speed is over a certain threshold, no compression is needed. Below the
 threshold compression method is chosen based on the graph for all
 available methods, like the first link above. When the speed is slightly
 below the threshold, fast and slight compressors are appropriate, like
 lz4. With slower speeds, deeper and slower compressors kick in, like zstd,
 and later lzma.

 I didn't see you even considering lz4 in proposal 278 references.
