Cc: Greg Lehey Content-Type: text/plain; charset="us-ascii" ; format="flowed" Sender: owner-freebsd-chat@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Folks, Some of you may remember some previous benchmarking I had done with vinum under FreeBSD 3.2-RELEASE against a DPT SmartRAID IV controller w/ 64MB of cache (see ). Well, I have recently updated those tests to include vinum under FreeBSD 4.1-STABLE and a DPT SmartRAID V controller w/ 16MB cache. I haven't updated the page listed above yet, because I wanted to get your feedback on what you thought these results might mean. I have my own views, but I'd like to hear yours. Anyway, the graphs are at (random read), and in that same directory there is also vinum-dpt-rw.png (random write), vinum-dpt-sr.png (sequential read), and vinum-dpt-sw.png (sequential write). I hope I did the conversion to PNG correctly -- neither of the web browsers I have seems to support this format, so I can't confirm for myself whether this looks correct or not. ;-) After a few days, I'll post my own ideas of what I think these results mean. -- These are my opinions -- not to be taken as official Skynet policy ====================================================================== Brad Knowles, || Belgacom Skynet SA/NV Systems Architect, Mail/News/FTP/Proxy Admin || Rue Colonel Bourg, 124 Phone/Fax: +32-2-706.13.11/12.49 || B-1140 Brussels http://www.skynet.be || Belgium "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
