Linux 5.0 File-System Benchmarks: Btrfs vs. EXT4 vs. F2FS vs. XFS

i don't see benchmarks of real workloads like 'create snapshot' or 'cp --reflink'

Patches of new test profiles/scripts always welcome for inclusion.

And what happens when KeePassX fills in a password in Firefox and that gets swapped out to disk? Or if it crashes and ends up in a coredump?

don't give physical access to adversaries
or encrypt swap
or don't use swap

But... reflink with XFS is stable or not?

It is on Btrfs. It works great.
I use alias cp='cp --reflink=auto' in my bash profile.

Of course, I use it with snapshots too, but I'm interested in XFS implementation, some month ago I red that reflink was in beta for XFS

I wonder what would be the results for ext4 after my usual tuning: noatime,nobarriers,data=writeback.
On the other hand, these optimizations mostly affect write performance, so read performance perhaps will remain the same?

I run plain unencrypted disks for all of my home PCs.

Me too. My laptop and other PC are unencrypted.

It is crazy to live in a physically and virtually unsafe place. Developing countries have fixed adsl lines and ip adresses, while modern countries have cheap care free 4G mobile networks. When I was using adsl, I had 100 attackers per day to my router firewall, with 3G/4G mobile networks zero.

Even modern countries still offer ADSL. Here in my country, it's still the second most used internet access technology (or whatever you call it) besides Fiber. And I do live in a modern, Western European country.

Is that safe to apply on SSD's? My SSD is modern (this is a 2018 laptop).
