You can cache and still preserve reproducability. What I'm planning for Copr is to do (every week/month)
  for chroot in fedora-20-x86_64 fedora-21_86_64 ... ; do
    mock --init $chroot
  done
take snapshot of that. I plan to do that on VM level.
And when new task come, I will just restore from that snapshot. And mock will start with already populated cache. So I
will have better caching and yet reproducability.
