Hi TPSReport - You realize that "gwf" is the Gary William Flake who has written an award winning complex book that is used in colleges worldwide as well as has run R&D for many companies like Microsoft, Yahoo, and Overture right? I'm sorry to say this but personally I'm finding your comments on this post as well other posts negative and lacking value. It would be great and helpful if you have any constructive/positive ideas, tips or experience to share to add value to the community. I'm sharing this in a positive constructive spirit. Thanks.

Let me reiterate my constructive suggestion that the OP provide actual data. I can see how the author wrote a pop book, as he is quite verbose, but any engineer can tell you that he is also quite evasive on technical questions. "What's the baseline?" should not pose a tough question for anyone writing about performance improvements.
