tiotest
tiotest(1) tiotest(1)
NAME
tiotest - Threaded I/O bench
SYNOPSIS
tiotest [-h] [-W] [-f SizeInMB] [-d TestDir] [-b BlkSizeInBytes] [-r NumberRandOpsPerThread] [-t NumberOfThreads] [-T] [-c] [-L] [-S] [-R]
[-D DebugLevel] [-k SkipTestNoN]
DESCRIPTION
tiotest is a file system benchmark especially designed to test
I/O performance with multiple running threads.
OPTIONS
-h Display a brief help and exit.
-W Instructs tiotest to wait for previous thread to finish before starting a new one in the writing phase. This results in the files
to be sequentially allocated and thus prevents them to be fragmented. Of course the writeside test is not parallel then but in
readside the files are physically more sequentially placed on the media (well this depends on the filesystem too).
-f SizeInMB
The filesize per threat in MBytes. Defaults to 10 MB.
-d TestDir
The directory in which to test. Defaults to ., the current directory.
-b BlkSizeInBytes
The blocksize in Bytes to use. Defaults to 4096.
-r NumberRandOpsPerThread
Random I/O operations per thread. Defaults to 1000.
-t NumberOfThreads
The number of concurrent test threads. Defaults to 4.
-T More terse output.
-c Consistency check data. This should be used for stresstesting the media rather than benchmarking (it will slow io and raise cpu
percentage). It is especially usefull to seek media for very hard to detect errors.
-L Hide latency output.
-S Do writing synchronously.
-R Use raw drives.
-D DebugLevel
Set the debug level.
-k fISkipTestNoN
Skip test number n. Could be used several times.
Example:
while tiotest -c -f 2000 ; do echo run ok ; done
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.
