Phoronix: Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10.

I am more and more considering XFS as an alternative to EXT4...

[Steffo]

I don't like regressions...

Why? Does XFS have better consistency and stability? Because EXT4 still seems to have "better"-ish performance (XFS is not far behind and does perform better than EXT4 in some benchmarks.)

Michael Is it somehow possible to also benchmark bcachefs (http://bcachefs.org/)?

You do? And this still confirms my thoughts that ext4 is still one of the best, well-rounded, standard purpose fs:es that has stood the test of time.
I won't be changing to anything else on standard boxes anytime soon.

You do know that XFS has been around just about as long as EXT ( 1992 for EXT vs XFS 1993 ). XFS was created by Silicon Graphics as a file system that could handle large, parallel data loads and has been the default file system for most supercomputers run today.

Also...Red Hat has now DEFAULTED to XFS on their Enterprise version of Red Hat. Suse has used XFS as default for years. XFS is now THE standard file systems for enterprise grade Linux and Unix computing. NOT ext.

That means XFS has also "stood the test of time"




XFS: The Enterprise File System of Choice

Few things in the Linux world get as much of a heated debate as the choice and usage of file systems. This debate has been raging long and hard between supporters of the major enterprise distributions for some years, with the two positions staked out being XFS and Ext4.
This conflict is about to change and thus bring some unity of thought to the major enterprise players.
Red Hat recently announced that RHEL 7 will likely have XFS as the default file system because “it’s a better match for our enterprise customers”stated Denise Dumas, Director of Software Engineering for Red Hat during an interview with TechTarget. This reflects a change from Ext4, the default file system used in RHEL 6 and an apparent departure from Red Hat charging for XFS support in their enterprise server product.
Interestingly enough, this brings Red Hat into alignment with the position that SUSE has been presenting for some time. For about the last 11 years, SUSE has been a fervent supporter of the use of XFS in the enterprise and has shied away from ext4, and we have been the recipient of a lot of criticism because of it.
SUSE has included XFS file system support at no cost since the release of SLES 8. This can be attributed to many reasons including scalability, performance and general robustness of the code. While this may have seemed a little edgy 11 years ago, SUSE based its decision on sound engineering and the belief that XFS offered a major value proposition to enterprise customers.
SUSE has avoided Ext4 due to concerns about scalability as the tools package only recently supported file systems in excess of 16TB. Ext4 also suffers from issues that require applications to be updated and make use of fsync calls to guarantee data is committed to disk. Applications that do not make proper use of these calls run the risk of data loss should a sudden power loss be experienced. While partially fixed with patches to the 2.6.30 kernel, concerns still persist with software that has not been updated to issue fsync calls when overwriting existing file data.
While it’s nice for SUSE to be vindicated for its choice of enterprise file systems, it’s even better that the community has found yet another thing on which it can agree: XFS as today’s enterprise file system of choice.

I am wondering if he could include bcachefs as comparision to the other filessystems (http://bcachefs.org)

Word of advice: look at tooling carefully before switching file systems. Hint: there are fewer utilities that will recover a bad XFS partitions than there are for EXT.
I went XFS for a while, but when I messed it up, it turned out it's not so great for my home use.

I don't like regressions...

If you're talking about XFS, it may be a different default somewhere, because it lost in one benchmark, but gained in a few others...

Only F2fs makes progression although it is not available as option to install any operating system

That's only true in the sense that only newer file systems make progress, while the established ones are in bug fixing mode already.
