[oi-dev] Slow Loader on Samsung 950 Pro

[Michal Nowak]

I noticed this very same issue under vSphere 6.7 U1 when fully updated hipster is installed to emulated NVMe device (on SSD disk).

I haven't seen it on vSphere 6.7, but I might be wrong. Release notes (https://docs.vmware.com/en/VMware-vSphere/6.7/rn/vsphere-esxi-671-release-notes.html) for 6.7 U1 says something about new NVMe feature, but it's not clear to me if they have guest or host device in mind.
