Linux 4.14 File-System Benchmarks: Btrfs, EXT4, F2FS, XFS

Linux 4.14 performance didn't really change for SQLite. Of these file-systems, XFS remains the fastest for SQLite while Btrfs with its default copy-on-write behavior is by far the slowest for databases like SQLite.

Random read performance didn't change with the exception of XFS now being a bit faster.

While on the random write front, the performance was unchanged.

The sequential read performance did see some fluctuations in these test conditions with XFS and EXT4 both being slower on Linux 4.14 while for this test Btrfs was the fastest.

But with sequential writes, there were no changes to report with FIO on Linux 4.14.
