Sun Solaris, OpenSolaris Sun Microsystems has delayed the release of two major features the company has trumpeted as reasons to try its latest version of the Solaris operating system. Eric Schrock, a Solaris kernel programmer, said on his blog in April that he's "completely redesigning the ZFS commands from the ground up" after finding some deficiencies.

I spent fifteen years doing photographic quality control for the US Navy prior to getting into IT. When you test a photographic system (camera, processing machine, etc.), the results tend to be specific to that system. Benchmarking computers is the same, even with the exact same components, the results will be similar but not the same. The results are specific for that machine, that OS, and that test. At best it is a generalization of how something will respond based on a given set of criteria.

Operating system benchmarks are some of the most complex, because to tune for one result skews another (if they were going to run the tests consecutively). And this is where the problems start, because most vendors don't like "out of the box" results (neither do I). So they tune, in some cases the tuning steps are made public, in other cases they are not.

I just don't see the point, each OS has strengths and weaknesses. Running a benchmark like iozone is pretty straightforward (, I do it all the time. What I recommend is you get some hardware and test for yourself. I found it to be an interesting experience.
