IOzone

IOzone is a file system benchmark utility.^[1]^[2] Originally made by William Norcott, further enhanced by Don Capps and others..

Source code is available from iozone.org. It does mmap() file I/O and uses POSIX Threads.

It won the 2007 Infoworld Bossie Awards for Best file I/O tool.^[3]^[4]

The Windows version of IOzone uses Cygwin. Builds are available for AIX, BSDI, HP-UX, IRIX, FreeBSD, Linux, OpenBSD, NetBSD, OSFV3, OSFV4, OSFV5, SCO OpenServer, Solaris, Mac OS X, Windows (95/98/Me/NT/2K/XP).

It is available as a test profile in the Phoronix Test Suite.^[5]
