Description

Fio is an open-source disk I/O benchmarking and stress testing tool for Linux, Windows, and OSX operating systems. It is designed to measure the performance of disk subsystems and to generate workloads that simulate the I/O patterns seen in real-world applications. Fio provides a range of parameters that can be used to customize the workloads and generate results that can be compared to other systems. It can generate multiple jobs in parallel, and provides support for a variety of I/O engines such as Linux’s native AIO (asynchronous I/O) and libaio, as well as the POSIX asynchronous I/O API. Additionally, Fio supports a variety of options for data patterns and I/O queue depths, allowing for more precise performance testing and tuning. Fio can be used to measure latency and throughput, as well as various other metrics such as IOPS and block size.
