squashfs-tools from Buster (1:4.3-12) is much slower than 1:4.3-8.0tails1
Compressing the SquashFS on lizard jumped from 20 min to 38 min since we upgraded from 1:4.3-8.0tails1.

I’m tentatively making this a release blocker because of the combination of two factors:
- Having our CI builds take about 30% more time has a painful impact on developer experience: our feedback loop is way too long already and there are not so many low-hanging fruits that would save 20 minutes.
- This problem seems to be https://bugs.debian.org/921146, which is fixed in sid, so it might be that this is cheap to fix. I’ll give it a try.

Regarding commit:c448a322b7784b7b0fa428197a5cdc218753b75c, it worked fine so far on lizard, my local Jenkins, and my own laptop (both with “ram” , “noram”, “defaultcomp noram”, and “defaultcomp ram” build options).
But none of these use the internal
apt-cacher-ng, and I’d rather not download GBs of data just to test this, so I’d appreciate if the reviewer used that one and tried the “ram defaultcomp” and “noram” build options (I’m assuming that it’ll give us enough coverage and one does not need to test each cell of the 2×2 matrix). Thanks in advance!
