It has support for 13 different types of I/O engines (sync, -mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, -solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, -forked or threaded jobs, and much more. It can work on block devices as well -as files. fio accepts job descriptions in a simple-to-understand text format. -Several example job files are included. fio displays all sorts of I/O -performance information. Fio is in wide use in many places, for both -benchmarking, QA, and verification purposes. It supports Linux, FreeBSD, -NetBSD, OS X, OpenSolaris, AIX, HP-UX, and Windows. - +fio is a tool that will spawn a number of threads or processes doing a +particular type of io action as specified by the user. fio takes a +number of global parameters, each inherited by the thread unless +otherwise parameters given to them overriding that setting is given. +The typical use of fio is to write a job file matching the io load +one wants to simulate.
