Since I'm the author of the article let me say - I agree with you. But let me also say that installing each of the approriate file systems would be difficult and very time consuming. I would love to do (file systems - if you are listening...) but I also need some hardware to do it. Any volunteers? More over, the file systems have their preferred hardware configurations for best performance. So a single hardware configuration may not be the most appropriate for all of the file systems (in addition, Panasas is a combined hardware/software solution so that make the comparison a bit more difficult). The intent of the article is a "survey." Just a quick review of what's available, some general "features" of the file system, perhaps how you configure it, etc. It's not intended as a review, since, as you have pointed out, there was no testing done. BTW - I'm working on a revision of the article. I hope to update it a bit and provide more technical details on the file systems. Also, I have real world experience with several of the file systems, but I haven't done any comparisons on performance. I was just curious to experiment with the file systems. Finally, don't let my limitations hold anyone back. if anyone wants to do some reviews/comparisons/etc. please feel free to do so and write up the results for ClusterMonkey (shameless plug there). If you need help with the comparisons, I'm glad to help. I'll even help write the article if you would like.
