Hi,
I'm not sure if we should switch to zstd, or if xz will do the work,
though I'd be delighted if the dpkg performances could be improved. I'm
spending all of my days installing server, sometimes with 1.5 TB of RAM
and 128 core (AMD Epyc...), on last gen NVMe, using a local mirror, it's
really painful to see how slow the debootstrap process is, compared to
what it could be. Unpacking multiple .deb at the same time seems a very
good idea to me, as well as parallelizing everything we can.
Just my 2 cents, as I wont be working on this,
Cheers,
