Content-Type: text/plain; charset="us-ascii" ; format="flowed" Sender: owner-freebsd-doc@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Folks, I originally posted this to freebsd-stable, and the suggestion was made to me that you folks might also be interested. Anyway, I've finally correlated some previous performance tests I had run a while back with rawio and vinum under FreeBSD 3.2-RELEASE. I gave these numbers to Greg at the time I collected them, but until now I had never actually put them into graphical format. See for the details of the test environment and links to the GIFs showing the final results. I am currently in the process of doing the second round of tests, although I have been forced to use a different machine as the test platform. This will obviously skew the results, but at least we should be able to get a pretty detailed look at how various different combinations of RAID-0, RAID-1, and RAID-5 compare performance-wise with vinum, and if I can manage to scare up one or more loaner hardware RAID controllers, I should also be able to compare software versus hardware. If you're interested, please let me know.
