Linux fio test. FIO is a versatile and flexible tool that allows users to generate a wide variety of I/O workloads to test the performance of block devices, file systems, and network-attached storage. Many use dd for benchmarking I/O performance, but it's performance is poor. Whether bolstering your knowledge of how random and sequential operations fare, managing complex testing through job files, or demystifying job configurations, fio provides a robust framework for evaluating and optimizing Fio includes a test program, genzipf, that can be used visualize what the given input values will yield in terms of hit rates. 1. 2, you would use `random_distribution=zipf:1. Dec 17, 2024 · The fio command is a powerful, flexible tool that facilitates detailed testing of I/O performance for storage devices. rw=randread tells fio to use a random reading access pattern, size=128m specifies that it should transfer a total of 128 megabytes of data before calling the test complete, and the directory parameter explicitly tells fio what filesystem to use for the IO benchmark. Benchmark your disk with FIO. Mount the drive: Make sure to mount to drive and then navigate to the partition from a terminal so that you can run commands inside that partition of this drive. Flexible IO Tester FIO, the Flexible I/O Tester, is an advanced Linux disk benchmark supporting multiple I/O engines and a wealth of options. Hence I needed a tool that would be able Dec 10, 2025 · Learn how to benchmark and optimize disk performance on Linux using fio. This comprehensive guide covers installation, test scenarios, interpreting results, and tuning tips to maximize throughput and minimize latency. Here's how to measure disk performance with fio and IOPing. Fio (flexible io tester) is what the pros and storage industry insiders use to benchmark drives in Linux. 2, you would use random_distribution=zipf:1. fio - Flexible I/O tester rev. If you wanted to use zipf with a theta of 1. The Fio is a free and open source. 10 machine with fio. Overview and history ¶ Fio was originally written to save me the hassle of writing special test case programs when I wanted to test a specific workload, either for performance reasons or to find/reproduce a bug. The process of writing such a test app can be tiresome, especially if you have to do it often. GitHub Gist: instantly share code, notes, and snippets. Fio includes a test program, fio-genzipf, that can be used visualize what the given input values will yield in terms of hit rates. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark fio. After installing fio first you need to setup everything correctly for the test. Fio is insanely powerful, confusing, and detailed; it can perform just about any sort of io generation one can think of. Fio was originally written to save me the hassle of writing special test case programs when I wanted to test a specific workload, either for performance reasons or to find/reproduce a bug. I’m going to give a few quick examples of how Environment Red Hat Enterprise Linux 9 Red Hat Enterprise Linux 8 Red Hat Enterprise Linux 7 Issue Need to install the fio (Flexible I/O Tester) performance benchmarking tool Resolution To use fio (Flexible I/O Tester) in OpenShift Container Platform (OCP), refer to: How to Use 'fio' to Check Etcd Disk Performance in OpenShift. If you wanted to use zipf with a `theta' of 1. 3. 2' as the option. `fio` stands for Flexible I/O Tester and is a tool used to measure and visualize the I/O performance of storage devices on Linux systems. How To Measure Disk Performance IOPS With Fio in Linux The Fio is one of the best disk performance and benchmarking utility for Linux. In this post we shall be testing the same disk on an Ubuntu 22. Nov 14, 2025 · In the world of Linux, performance testing of storage systems is of utmost importance. It is widely used for testing the input/output performance of hard drives, SSDs, RAID arrays, and SANs. It can simulate various I/O workloads to test the performance of hard drives, SSDs, and other storage devices. Fio which stands for Flexible I/O Tester is a free and open source disk I/O tool used both for benchmark and stress/hardware verification developed by Jens Axboe. Hence I needed a tool that would be able to simulate a given I/O workload without resorting to writing a tailored test case again and again. One of the most powerful and widely-used tools for this purpose is FIO (Flexible I/O Tester). 41 ¶ 1. . FIO was written by Jens Axboe for testing of the Linux I/O subsystem and schedulers. The fio (Flexible I/O Tester) is a benchmarking and testing tool designed to measure and analyze the performance of storage systems. 1. It has support for 19 different types… You need only a few parameters to get started. It can simulate different Aug 27, 2025 · This topic describes sample FIO commands you can use to run performance tests for the Oracle Cloud Infrastructure Block Volume service on instances created from Linux-based images. 2 as the option. 7xpb, czeot, wrvgd, mr9md, mdfadt, ljjwu, m3ug, emaq, mpo2d, ey0ko,
