Bonnie++ - NEW!
Greatly improved disk I/O benchmark based on the code for Bonnie by Tim Bray. Bonnie++, rewritten in C++ by Russell Coker (russell@coker.com.au), adds the facility to test more than 2Gb of storage on 32-bit machines, and tests for file creat(), stat(), unlink() operations.
Bonnie v.2.0.6
One of the best "open systems" benchmarks available. It can be compiled under different UNIX flavors. We have successfully run it under SCO UNIX, Linux, Solaris, and BSDI. It should also compile with minimal changes under other UNIXes.
IOzone - UPDATED
Another great benchmark, in our opinion. The benchmark generates and measures a variety of file operations. IOzone is useful for performing broad filesystem analysis of a vendor's computer platform. It can also be used for NFS performance testing and the latest version now supports cluster testing as well. IOzone had been ported to numerous UNIX OSes and Windows NT. Read more about it and download the source by clicking on the link above.
Xbench - NEW!
Xbench is a a comprehensive benchmarking solution for Mac OS X. In addition to various system component benchmarks, it provides performance testing capabilities for sequential and random uncached disk I/O performance.
IOstone v. C/II
IOstone is a multi-platform disk, file I/O and buffer cache efficiencies benchmark program. This benchmark was originally created for UNIX and later ported to OS/2 and DOS. Included in this archive are the OS/2 and DOS executables with source code.
Disktest
Disktest allows any direct access device (and some sequential devices) to be tested while UNIX is still available to other users. Care should be taken to make the device which is to be tested unavailable to other system users.
IOBENCH
Excellent I/O throughput and fixed workload benchmark for UNIX. There are two versions of IOBENCH contained in sub-directories of this directory. These two versions contain the same source files and differ only in the scripts that drive the benchmark. Directory 073.iobench contains the throughput variant; directory 084.iobenchpf contains the fixed workload variant. This is the SPEC 2.6 distribution of IOBENCH.
IOCALL
IOCALL measures OS performance, in fact that is nearly all it measures. It also concentrates on system call interface efficiency, and especially read() system call performance, the most used system call on most systems. IOCALL is intended for UNIX systems only.
RawIO - NEW
Low-level raw device benchmarking program written by Greg Lehey, the author of the book "The Complete FreeBSD", published by Walnut Creek. This benchmark will only compile under BSD as it uses BSD specific mmap() call. Port to Linux is currently in progress.
A new benchmark to measure performance of e-mail, netnews, and e-commerce classes of applications. PostMark was created to simulate heavy small-file system loads with a minimal amount of software and configuration effort and to provide complete reproducibility. It can be compiled under Solaris, Digital Unix, and Win32 environments. Learn more about the PostMark and download the source code by following the link above.
Nbench
A very nice little benchmarking program for Windows NT. Nbench reports the following components of performance:
- CPU speed: integer and floating operations/sec
- L1 and L2 cache speeds: MB/sec
- main memory speed: MB/sec
- disk read and write speeds: MB/sec
NTiogen 1.03 - UPDATED
NTiogen benchmark was written by Symbios Logic. It's Windows NT port of their popular UNIX benchmark IOGEN. NTIOGEN is the parent processes that spawns the specified number of IOGEN processes that actually do the I/O.
The program will display as output the number of processes, the average response time, the number of I/O operations per second, and the number of KBytes per second.
IOmeter - UPDATED
This benchmark was originally written by Intel. Intel has discontinued the development and released the source code into public domain. SOURCEFORGE.NET is currently hosting this project. IOMETER is a disk I/O subsystem measurement and characterization tool for single and clustered systems. Iometer does for a computer's I/O subsystem what a dynamometer does for an engine: it measures performance under a controlled load. It is now available for Windows 2000, Linux, and Solaris.
Bench32
A very comprehensive benchmark that measures overall system performance under Windows NT or Windows 95. Unfortunately, the company that wrote this benchmarking program seems to have gone out of business. You can find a local copy of Bench32 v.1.21 here.
ThreadMark
A very popular benchmark written by Adaptec. Adaptec's decided that they cannot support it anymore and thus they have removed this benchmark from their web site. Click on the link to download ThreadMark from our server.
Shareware/commercial disk I/O benchmark. HD Tach is a physical performance hard drive test for Windows 95/98 and Windows NT. In Windows 95/98 it uses a special kernel mode VXD to get maximum accuracy by bypassing the file system. A similar mechanism is used in Windows NT. HD Tach reads from areas all over the hard drive and reports its average speed. It also logs the read speeds to a text file that you can load into a spreadsheet and graph to visually read the results of the test.
SCSITool - NEW
A very comprehensive diagnostics and benchmarking tool for SCSI storage devices. Currently supported device types are: harddisk, tape, cd-rom, optical and removable disks. Learn more about the SCSITool and download the program by following the link above.
RAIDmark
The only benchmark we have found that was specifically created to measure the performance of RAID arrays. RAIDmark benchmarking program by DynaTek Automation Systems Inc., measures cache size, system overhead, and application-level performance. Includes MS-DOS and Novell versions. Unfortunately, the source code is not included. As far as we know, this was the last release of RAIDmark; DynaTek no longer supports or does any development of this benchmarking program.
Qbench
DOS hard disk benchmark from Quantum Corporation which measures data access time and data transfer rate. Just a nice little benchmark for quick results. No source code included.
DOS disk benchmarking program created by CORE International. CORE Disk Performance Benchmark is distributed as a DOS binary, no source code included.
