Maybe I had an old appliance:
rm -rf /var/tmp/.guestfs-1000/ && bash ./run tests/qemu/boot-analysis
I should've used this instead to take advantage of new supermin:
rm -rf tmp && bash ./run tests/qemu/boot-analysis
I've rebuilt libguestfs from the branch above and now I get 3.17s on Debian with the 4.3 kernel:
Still slower than yours, but could be due to different kernel/qemu versions, or could indeed be due to CPU.
