Phoronix: 6-Way File-System Comparison On The Linux 4.1 Kernel

With the Linux 4.1 kernel having recently been released, I decided to conduct a fresh round of file-system comparisons on this new kernel using a solid-state drive. The file-systems tested in this article were the in-tree EXT4, Btrfs, XFS, F2FS, ReiserFS, and NILFS2 file-systems while a follow-up article will take a look at the out-of-tree contenders like Reiser4 and ZFS atop Linux 4.1.

Thank you Michael, I really like these articles. Would it be possible to include in the same graphs for each file system 2 bars, one for the previous linux version to compare?

I was using xfs, but recently switched to ext4, with plans for switch to btrfs(I will wait for it to stabilize a bit before the jump)

I'm more than happy with EXT4.

I've been planning to setup a Btrfs-based file server for my home for the past year. I'm just waiting for RAID5/6 to stabilize. I finally feel though it is relatively close, should happen within the next 2-3 kernel releases.

I'm currently using ext4, and I'll probably stick to that for root partition, but I've been looking to move my data/media partition to btrfs for easier backup management.

I was happy with xfs, too, until I messed up my partition table (my fault, not file system's). At that point I have discovered that while there are tools that will help you recover an ext partition, hardly any will work for xfs. Plus, as I read in the meantime, xfs's strength is handling huge files. And I don't edit video.

Back to the article, it's nice, but the picture is more complex. I'd throw a mechanical drive in there, because the best file system for a SSD will not necessarily perform the same on a HDD. And many people still use those for storage. I'd also test using SSDs with controllers from different manufacturers, there may be a few surprises in that area.

Why mount btrfs nodatacow instead of using chattr +C on the relevant directory?

For databases? In the case of automated tests, etc, or if that partition is just used for database storage only.

For this particular test, no, as I only had time to test this particular SSD on Linux 4.1 before re-tasking it to a different system, etc. It really depends on the interest level and related interest of recent articles whether it's a multi-way kernel comparison article, etc.
