1.1. Performance Tuning Examples

Several places in this book cite real performance numbers that I measured on a test network. It is appropriate that some information be provided up front about the system and test methodology used in arriving at the data presented in this book.

The systems used to generate the data found in this book are not configurations that I would recommend using in actual practice. This discrepancy is intentional. I selected these particular configurations as test platforms for the following reasons:

  1. It is important to understand how performance can be affected in both CPU-bound and I/O-bound server situations. Therefore, I use server configurations that have been artificially manipulated to be CPU bound and I/O bound. ...
