WebBTRFS is still a bit off from NTFS in Windows, but in some runs, it actually beats in 4k random reads. Some performance degradation is to be expected, not being a native FS and having to work around MS BS. Top is BTRFS, bottom is NTFS, IDK if 4k measuring is broken, but the completion time was still fast, so I assume its measuring is just bugged.

Performance-wise I did not notice a major difference. scratch one night at flumpty\u0027s 2WebAs a btrfs volume ages, its performance may degrade. This is because btrfs is a Copy On Write file system, and all COW filesystems eventually reach a heavily fragmented state—including ZFS, where free space becomes fragmented. Over time, frequently appended or updated-in-place files will become split across tens of thousands of extents. scratch one flattop meaning
