fio 2.1 發布，I/O壓力測試工具

fio是一個I/O工具，可用于硬件的基準和壓力測試工具。支持13種不同的I/O引擎，包括：sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio 等等, I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, 等等。 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, OS X, OpenSolaris, AIX, HP-UX, and Windows。

發布日志: Integration of the gfio GTK frontend. Better Android integration. The initial file fill honors data compression settings. An option for controlling randomness of I/O (percentage_random) instead of being fully random or fully sequential. Fixes a bug in uneven pattern sizes for verification. Various other important fixes
