Chris,
Thanks for your feedback and comments, it's very valuable to me.
In my previous message, I mentioned that CPU is *underutilized* during installation. I haven't investigated further why, but I suspect it's due to the inefficiency caused by the usage of the *loop* device and/or inefficiency in the rsync itself.
We might be able to do somewith nbdkit inside the installer to transparently uncompress and loop mount at the same time. (Although this would require xz, not zstd because of a missing feature in zstd - see my other comment in this thread).
Rich.
