Hi Dr. Philip,
Thank you very much for your explanation. It's nice to know you are
still watching squashfs-tools, and let us know where the problem is for
the package squashfs-tools in the Debian repository. I salute you.
Appreciate.
Steven

Hi Steven,
The reason why the hacked Debian version of Mksquashfs performs badly
is because the Debian "maintainer" has applied a so called
reproducibility patch that *completely* breaks the parallelism in
Mksquashfs.
The offending patch is 0016-remove-frag_deflator_thread.patch

As Squashfs author and maintainer I would not recommend *anyone* to
use the squashfs-tools currently packaged by Debian.
As for "squashfs-tools-ng", this is a rogue project masquerading as an
official new upstream. It is neither official nor a new upstream. As
Squashfs author and maintainer I completely disassociate that project
with the Squashfs project.
I have publicly stated that this project is spreading falsehoods and
that it is defamatory to me as the Squashfs author and maintainer.
