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

Lastly is a look at the start-up time of some applications while having various I/O occur in the background.

The startup-time results are most interesting here for the Flash-Friendly File-System. With these tests, F2FS was across the board winning with all three storage configurations.

These file-system results end up being similar to what we've seen out of recent comparisons on older kernels: generally F2FS and XFS are the fastest on the consumer solid-state storage devices generally followed quite quickly (and commonly trading blows) with EXT4. Btrfs with its copy-on-write behavior leads to it having a lot of features but at least in its out-of-the-box behavior generally being a fair amount slower than EXT4/F2FS/XFS. Perhaps most interesting from today's results were the startup-time application results where the Flash-Friendly File-System easily won across all of those tests.
