Brannon Tue, 05 Oct 2010 22:51:50 +0000 http://www.cyberciti.biz/tips/?p=2437#comment-160059 I came across a paper that might help you determine the right record and file system parameters to give iozone for a given storage usage situation. It is quite detailed, but simply skimming it should help you provide better testing parameters than simply copying someone else's or choosing them randomly. Generating Realistic Impressions for File-System Benchmarking Nitin Agrawal, Andrea C. Arpaci-Dusseau, Remzi H.

However, I wonder how to determine the right file size and record size to test for our application? Very nice tool.
