IOzone
IOzone is a filesystem benchmark tool that generates and
measures a wide variety of file operations. Iozone has been ported to
many machines and runs under a variety of operating systems.
Iozone is useful for determining a broad filesystem analysis
of a vendor's computer platform. The benchmark tests file I/O
performance for the following operations: Read, write, re-read,
re-write, read backwards,
read strided, fread, fwrite, random read/write, pread/pwrite variants.

Features include:
- POSIX async I/O - uses the POSIX standard async I/O
interfaces to accomplish this
- Mmap() file I/O - map a file into a user’s address space.
Once this mapping is in place then stores to this location in memory
will result in the data being stored going to a file
- Normal file I/O
- Single stream measurement
- Multiple stream measurement
- Distributed fileserver measurements (Cluster)
- POSIX pthreads
- Multi-process measurement
- Excel importable output for graph generation
- Latency plots
- 64bit compatible source
- Large file compatible
- Stonewalling in throughput tests to eliminate straggler
effects
- Processor cache size configurable
- Selectable measurements with fsync, O_SYNC
- Builds 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)
