Filesystem benchmark tools- IOzone
Last few days am doing my own research related to disks, i/o etc.. All theory is just theory until you prove it.. so best way to do it is to run some tests and collect information .. Fortunately for us there are free benchmark tools.
Today I got a chance to play with IOzone ( thanks to my Linux admin) and would like to share few key points when using this tool..
Tool can be downloaded from IOzone site www.iozone.org
After installing it I got latest version Version $Revision: 3.311 $ Compiled for 64 bit mode.
so fastest way to get help
iozone -h and iozone -a to run in auto mode.
From my qiuick play with tool:
a) tool have zillions options.
b) can generate output file in Excel format .. means nice graphs..
e.g.
iozone -ab test.xls ( a – auto mode , b – generate Excel file )
Output looks something like this.. I uploaded picture from IOzone site..

Check out what others are saying...[...] how to graph iozone output using OpenOffice? Hi all, Can anyone please steer me in the right direction with this one? I've searched the net, but couldn't find a clear answer. How do I actually generate graphs from iozone, using OpenOffice? Every website I've been to simply mentions that iozone can output an xls file which can be used in MS Excel to generate a 3D graph. But, I can't see how it's actually done. Can anyone please help me with this? I've run the following command on a CentOS 5.4 server: iozone -R -l 5 -u 5 -r 1m -s 100m -F /home/f1 /home/f2 /home/f3 /home/f4 /home/f5 | tee -a /tmp/iozone_results.txt & And then imported the iozone_results.tx file into OpenOffice Calc, but got no idea where to from here? I would like todo something like this: http://www.smallnetbuilder.com/image…m_read_big.png http://oraclue.com/2008/10/03/iozone…benchmark-too/ [...]
