Not on an average VM (8 threads and 16gb memory) or network (100gbit), but ceph isn’t average solution.
For my link archive this long Twitter thread:
Archive.is Kristian Köhntopp on Twitter: “Playing with a Ceph Storage Volume in a VM: The new openstack backend provisions an all-flash Ceph volume, which after tuning delivers a commit latency of around 1.1ms or so. My dev VM has 8 Threads and 16 GB of memory, and mounts the Ceph Volume with XFS in /a.”
Hopefully this one day makes into a blog post at [Wayback] Die wunderbare Welt von Isotopp | Something old, something new, something borrowed, something blue.

Mid 2020, I re-installed a Raspberry Pi 2 box based on OpenSuSE Tumbleweed.
To my susprise the yast2 module sudo could not write the configuration.
It appeared that /etc/sudoers had become readonly and a new /etc/sudoers.d was created.
You can use visudo to edit files in that directory without potentially losing changes in /etc/sudoers during upgrades. I think that is a good move.
To bad the yast module failed because of it.
More on visudo and the /etc/sudoers.d directory:
