Summary: A flexible I/O tester/benchmarker

Description:
fio is an I/O tool meant to be used both for benchmark and
stress/hardware verification.
It has support for 9 different types of I/O engines
(sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet),
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.
