Fio is a flexible I/O benchmarking and workload simulation tool that spawns threads or processes performing user-defined I/O patterns via job files. It was written by Jens Axboe to test storage performance and reproduce I/O bugs without writing custom test programs.
Use cases
- benchmark disk or SSD throughput and latency
- simulate random and sequential read/write workloads
- reproduce storage I/O bugs with reproducible job files
- test filesystem and block layer performance under load
- measure effects of different I/O schedulers
- stress test storage with async I/O and multiple threads
When to choose
- you need flexible, scriptable storage I/O benchmarking on Linux
- you want to simulate realistic application I/O patterns
- you are tuning or comparing storage hardware or filesystems
When to avoid
- you need application-level or network benchmarking rather than I/O
- you want a simple GUI-based disk benchmark
