I'm terribly sorry, but this information is practically useless. There
are no version numbers, no information about configuration, about
backing stores, disk image formats, cache settings, and very little
about hardware, etc. I can't e.g. tell if your factor 8 drop i
performance on Ubuntu for small writes is due to the virtual disk
being backed by a qcow2 on ext4, for instance, and as such, I can't
use the data (and much less the conclusions) for anything.
