RE: raw versus Mounted File Systems
Vivek - There used to be a good paper on Oracle's website. The paper asked the question: If benchmarks show raw to be faster that file systems, why don't you see a difference in production? The answer the paper provided is that on a well-tuned OLTP system, disk isn't the bottleneck. There are many users performing many different tasks simultaneously, and not everyone is sitting around waiting for disk. I looked around on Oracle's Web site, but I can't find the paper there now. Maybe someone else will recall this paper. Dennis Williams DBA, 40%OCP Lifetouch, Inc.

RE: raw versus Mounted File Systems
Mark - Thanks very much. You are right, that Cary guy really nails those performance issues. The original paper date is 1992.
