Public bug reported: I have had a problem where importing database was much slower in a dual- boot machine when booted into ubuntu compared to running ubuntu inside virtualbox in windows 10. It seems Ubuntu does not like Amd carrizo fch
I collected some information and posted here (and attached as text file to report): https://answers.launchpad.net/ubuntu/+question/360373 To put it short, the disk performs up to 10 times better inside virtualbox. (yes I thought about caches but VM box also has half the memory and they must favor ubuntu running on real hardware with twice ram....) I believe this is a kernel/driver related problem since it directly effects disk performance.
