Corrected a mistake that caused the altivec test to be turned off on PowerPC machines.Xbench is accompanied by a website that allows graphical side-by-side comparison of any out of thousands of submitted benchmarks. We will post the results here when we get an adequate number of responses.Xbench is useful not only for comparing the relative speeds of two different Macintoshes, but also for optimizing performance on a single machine. If you would like to send us the results of running any of the above benchmarks on your hardware, please feel free to do so. Please check this page often because we will add more I/O benchmarking programs as we find them. DON’T just rely on benchmark results! We hope you will find these benchmark programs helpful. If at all possible, always try to test a storage device offered to you in YOUR APPLICATION environment. You can get great I/O performance results as indicated by one of the benchmarks but in a REAL APPLICATION environment at your company, the performance can be not at all up to par. This will give you results which can be compared against each other, thus giving you an opportunity to buy a storage solution that is right for YOUR company. To overcome this, you can download one of the benchmarks for "open systems" we have here and then run it with different vendors' storage devices. This makes it very hard to compare different products from different vendors. They use proprietary benchmarks or their benchmarks get tuned to their particular storage device. Very often, it is very hard to get objective I/O performance results from your storage vendor. There are tools available for benchmarking various other system components. Notes: Please note that we have only collected benchmarks for measuring I/O performance. Learn more about the PostMark and download the source code by following the link above. It can be compiled under Solaris, Digital Unix, and Win32 environments. PostMark was created to simulate heavy small-file system loads with a minimal amount of software and configuration effort and to provide complete reproducibility. IOCALL is intended for UNIX systems only.Ī new benchmark to measure performance of e-mail, netnews, and e-commerce classes of applications. It also concentrates on system call interface efficiency, and especially read() system call performance, the most used system call on most systems. IOCALL measures OS performance, in fact that is nearly all it measures. This is the SPEC 2.6 distribution of IOBENCH. Directory 073.iobench contains the throughput variant directory 084.iobenchpf contains the fixed workload variant. These two versions contain the same source files and differ only in the scripts that drive the benchmark. There are two versions of IOBENCH contained in sub-directories of this directory. Care should be taken to make the device which is to be tested unavailable to other system users.Įxcellent I/O throughput and fixed workload benchmark for UNIX. Included in this archive are the OS/2 and DOS executables with source code.ĭisktest allows any direct access device (and some sequential devices) to be tested while UNIX is still available to other users. This benchmark was originally created for UNIX and later ported to OS/2 and DOS. IOstone is a multi-platform disk, file I/O and buffer cache efficiencies benchmark program. In addition to various system component benchmarks, it provides performance testing capabilities for sequential and random uncached disk I/O performance. Xbench is a a comprehensive benchmarking solution for Mac OS X. Read more about it and download the source by clicking on the link above. IOzone had been ported to numerous UNIX OSes and Windows NT. It can also be used for NFS performance testing and the latest version now supports cluster testing as well. IOzone is useful for performing broad filesystem analysis of a vendor's computer platform. The benchmark generates and measures a variety of file operations. It should also compile with minimal changes under other UNIXes.Īnother great benchmark, in our opinion. We have successfully run it under SCO UNIX, Linux, Solaris, and BSDI. It can be compiled under different UNIX flavors. One of the best "open systems" benchmarks available. Bonnie++, rewritten in C++ by Russell Coker adds the facility to test more than 2Gb of storage on 32-bit machines, and tests for file creat(), stat(), unlink() operations. Greatly improved disk I/O benchmark based on the code for Bonnie by Tim Bray. It supports Linux, FreeBSD, NetBSD, OS X, OpenSolaris, AIX, HP-UX, and Windows. It has support for 13 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3,splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more. Fio is an I/O tool meant to be used both for benchmark and stress/hardware verification.
