Re: Filesystem benchmarks




And with a quick look the benchmark seems to make some simplifying
assumptions that may or may not match your application needs.  He also
did not report or tune any of the file systems mkfs params.

"Individual filesystem configuration is documented <a>here</a>." Points to: http://www.untroubled.org/benchmarking/2004-04/filesystems.html

For example in the mke2fs man page: If omitted, mke2fs block- size is hueristically determined by the file system size and the expected usage of the filesystem (see the -T option)." So we do not know exactly how his ext3 filesystems (and others) were tuned. The hueristics could be researched and we could discover the resulting parameters but at this moment we do not exactly know.

To his credit he clearly exposes his method, data and goals.
Very good stuff!
