Public bug reported: Recently makedumpfile had zstd[0] support added upstream[1]. My suggestion here is to backport this work for Debian/Ubuntu and use it as default (starting for example in 22.04), since it has a better compression time and similar or even better compression rate. In [1] there are good experiments, but I did a simple experiment in a small VM (2G of RAM, idle) using Debian 11 (results in the first comment].
I'll open a Debian bug as well.
