The random read performance with FIO was a race between EXT4, F2FS, and XFS. Btrfs was the slowest and with copy-on-write disabled was only providing marginally better performance on Linux 7.0.

👁 Flexible IO Tester benchmark with settings of Type: Random Write, Engine: IO_uring, Direct: No, Block Size: 4KB, Job Count: 8, Disk Target: Default Test Directory. XFS was the fastest.

👁 Flexible IO Tester benchmark with settings of Type: Random Write, Engine: IO_uring, Direct: Yes, Block Size: 4KB, Job Count: 32, Disk Target: Default Test Directory. EXT4 was the fastest.

FIO with 4K random writes continues to be typically led by XFS while EXT4 also picked up an occasional win.

👁 Flexible IO Tester benchmark with settings of Type: Sequential Write, Engine: IO_uring, Direct: No, Block Size: 2MB, Job Count: 16, Disk Target: Default Test Directory. XFS was the fastest.

👁 Flexible IO Tester benchmark with settings of Type: Sequential Write, Engine: IO_uring, Direct: No, Block Size: 2MB, Job Count: 64, Disk Target: Default Test Directory. XFS was the fastest.

For sequential writes, XFS was enjoying a huge lead over the other file-systems on this AMD EPYC Turin server with PCIe Gen 5.0 NVMe SSD storage.
