On the record
- Benchmark profile
- The default profile uses sequential 1 MiB tests at queue depths 8 and 1, and random 4 KiB tests at queue depths 32 and 1, each with one thread.github.com · read 5 Oct 2026
- Cache clearing
- It attempts to clear disk caches before read tests using operating-system-specific methods when permissions allow; sudo is optional and recommended for this.github.com · read 5 Oct 2026
- Comparability
- The maker advises using results to compare performance within the same operating-system environment because results across operating systems should not be directly compared.github.com · read 5 Oct 2026
- Compatibility limit
- The README advises against directly comparing results across operating systems because storage stacks, hardware interfaces, fio engines, and filesystems can affect results.github.com · read 5 Oct 2026
- Customization
- Options include the target directory, test file size, number of rounds, benchmark type (read, write, or both), and verbose output.github.com · read 5 Oct 2026
