Nice to have more benchmarks. Maybe you can write up something for the wiki?.. Funny you should mention that - I was speaking with a colleague recently and I told him that I'm going to try for a fairly comprehensive test of raid5, raid10[n2,o2,f2] in both regular and degraded mode, utilizing fstest to test ext3, jfs, xfs, and maybe spadfs. I've got most of it scripted too so some refinements to those scripts might be useful to somebody else. I plan on putting this on my blog when I get the time. However, I'm rather pressed for time right now so it will likely be a while.
Such is life. So then, when this is out, could I then use your findings for the wiki? I think the wiki is a good place to put up such tests, as more people would have a chance finding the results there. best regards Keld -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
