For the write performance, Btrfs and XFS is performing almost identical with a throughput just below 270 MB/s (see Figure 14). It's quite fast and excels at large file performance (much better than either EXT3 or EXT4, and far better than ZFS or BtrFS, but with obvious risks being non-next-gen). This is an important observation if you’re considering deploying XFS on smaller instances in the hope of improved performance.
