RE: Raw partition Vs File System

Hi All,

Does anyone have an email address for Bert? I looked for his email address when I first read that article a week ago,
but did not find one. I think I know what was wrong with his test, but it is hard to be sure because he left out a lot
of the details.

Did anyone read Bert Scalzo's article in Pipeline Newsletter this month (http://www.revealnet.com/newsletter-v2/linux2.html)? He was benchmarking various filesystems under Linux (EXT2, EXT3, Reiser, IBM JFS and RAW). I was suprised (and so was he) to see worst performance on RAW devices. I presume this is a Linux-specific issue: can anyone suggest why RAW is so poor on Linux (or want to contest the results?!)

Thanks
- Bill.
