tiobench(1) tiobench(1)NAMEtiobench - Threaded I/O benchSYNOPSIStiobench [--help] [--nofrag] [--size SizeInMB [--size ...]] [--numruns NumberOfRuns [--numruns ...]] [--dir TestDir [--dir ...]] [--block BlkSizeInBytes [--block ...]] [--random NumberRandOpsPerThread [--random ...]] [--threads NumberOfThreads [--threads ...]]DESCRIPTIONtiobench is a perl wrapper to tiotest calling it multiple times with varying sets of parameters as instructed. OPTIONS --help Display a brief help and exit. --nofrag Instructs tiobench to pass -W to tiotest so it waits for previous threads to finish before starting a new one in the writing phase. For more info see the -W option in the tiotest(1) manpage. --size SizeInMB The total size in MBytes of the files may use together. If this option is not given, tiobench tries to be smart and figure out a size making sense. --numruns NumberOfRuns This number specifies over how many runs each test should be averaged. Defaults to 1. --dir TestDir The directory in which to test. Defaults to ., the current directory. --block BlkSizeInBytes The blocksize in Bytes to use. Defaults to 4096. --random NumberRandOpsPerThread Random I/O operations per thread. Defaults to 1000. --threads NumberOfThreads The number of concurrent test threads. Defaults to 4. The options --size, --numruns, --dir, --block, --random, and --threads may be given multiple times to cover multiple cases, for instance: tiobench --block 4096 --block 8192 will first run through with a 4KB block size and then again with a 8KB block size. To get usefull results the used file sizes should be a lot larger than the physical amount of memory you have. A good idea is to boot with 16 Megs of RAM (Try passing the "mem=16M" option to the kernel to limit Linux to using a very small amount of memory) and into Single User mode only.SEE ALSOtiotest(1), bonnie(1), hdparm(8)AUTHORtiobench was written by James Manning <jmm@computer.org>.
