Projeto Descrição

fio is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 19 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, including complete IO latencies and percentiles. Fio is in wide use in many places, for both benchmarking, QA, and verification purposes. It supports Linux, FreeBSD, NetBSD, OpenBSD, OS X, OpenSolaris, AIX, HP-UX, Android, and Windows.

Realizou-se uma grande reformulação, dividindo as extremidades frontais e traseira. Fio agora pode ser executado como um servidor e um cliente, e é possível controlar trabalhos em várias máquinas de um único cliente. Baratos e simples dados lutando agora são usados por padrão para derrotar SSD compressão/duplicação. Foi adicionado suporte a auto-completar latência percentil. O formato de saída concisa foi revisto para a versão 3, adicionando percentis de utilização, IOPS e latência de disco. Padrão verifica foram acelerou. Várias correções foram incluídas para FreeBSD, Windows, HP-UX, Mac OS X e AIX.
A major overhaul was undertaken, splitting the front and back ends. Fio can now be run as a server and a client, and it is possible to control jobs on multiple machines from a single client. Cheap and simple data scrambling is now used by default to defeat SSD compression/de-duplication. Completion latency percentile support was added. The terse output format was revised to version 3, adding disk utilization, IOPS, and latency percentiles. Pattern verifies were sped up. Various fixes were included for FreeBSD, Windows, HP-UX, Mac OS X, and AIX.
