Hi Marcel,
Hi Ray,
Please have a look on this thread, I think Laszlo and Paolo found the root cause. https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg01368.html It seems hot-plugging the devices would not help.
Thanks, MArcel
Yup - I am using Seabios by default. I took all the measures from the Kernel time reported in syslog. As Seabios wasn't exhibiting any obvious scaling problem.

It is an issue worth looking into it, one more question, all the measurements are from OS boot? Do you use SeaBIOS? No problems with the firmware?
Thanks, Marcel
