Based on the results above, I'd suggest selecting the following
''optimal configuration'': XZ algorithm, with block size of 1MiB and
without BCJ filter (plain xz -b 1M, without -Xbcj x86).
On the right, you can see the impact of the compression algorithms on
installation time.
Why XZ as opposed to, say, ZSTD?
The latter is already available in squashfs-tools as of July 2019:
