Python version Topics. Fio used 4k block sizes, that means a 128/4=32 time write amplification. It has a huge number of plugins (“engines”) for different APIs (standard POSIX, libaio, uring, etc) and is widely used to test single-node performance for storage devices and appliances. dat - that deletes the file after its been used The output file - see --output (at the end) that defines where the results go Mar 10, 2024 · fio is the industry standard way to test performance of a disk. Environment. We are going to perform a random write, read and read and write test. The write speed. biz – alternate way of testing disk performance by using “dd” command (server throughput and latency). Test notes: * It'll take time to run the test based upon settings chosen. Multiple fio jobs for direct I/O, even though using sequential read or write operations, can result in lower than expected throughput for st1 and sc1 volumes. 02GB and bandwidth 875mbits/sec Oct 1, 2020 · To get started, select the disk from the top drop-down (it defaults to the disk holding your home directory), then click on All to perform all the available tests.

Therefore, it is important to regularly test the disk speed of your server to ensure optimal FIO, the Flexible I/O Tester, is an advanced Linux disk benchmark supporting multiple I/O engines and a wealth of options. In this guide, I will show how to use fio to measure the speed of data reads/writes on storage devices. ) and got just over 100 MB/s which left me puzzled. 9tb using 15k rpm disks so moving the data of the file shares would really help me out, Right now i got a baseline on the current setup getting around 49mb/s read and 111mb/s writes and ran iperf getting transfer speed 1. I will run an FIO speed test and normally the first time after building the raid/booting it will get the speeds it should around 25gb/s and maintain it as long as I let the test run. Sau khi đã chạy đoạn script ở trên, bạn hãy chú ý đến thông số “dd Test” và “Fio Test” Disk Speed ----- dd Test I/O (1st run) : 567 MB/s I/O (2nd run) : 961 MB/s I/O (3rd run) : 1. Sep 18, 2020 · I guess you still used your original fio command if it took an hour.
