The switch of mock might have affected which kind of build-container it defaults to.
The switch to cgroup-v2 might have affected how the systemd-containers are working.
Maybe you can try to force it to chroot to have the container as thin as possible.

I've noticed the same problem but I'm not sure it's about the packages. It may be something to do with mock or the kernel, possibly. Are you running Rawhide on the machine where you're doing the mock builds?
I'm building for rawhide, but on my F32 desktop...
I most recently noticed it when building lives with Python 3.9 for testing - that should take less than an hour per image, it actually took 12+ hours per image. When I attach an strace to the dnf process it seems like it doesn't really stick on any one call for a *long* time, but it seems to do a lot of fsyncs, and each one takes, like, a half second or so. I *think* the slowness is the result of all those fsyncs piling up.
The actual package build time doesn't "feel" any difference, but installing the dependencies definitely takes much longer.
I've tried installing nosync (both i686 and x86-64) on the host but it didn't seem to make a difference, I didn't check for sure that it actually kicked in. I'll try and do a bit more of a systematic look at it tomorrow, since at least now I know I'm not the only one...
I have nosync (both arches) installed as well...
Thanks,Richard
