John Goodson, "The Data Access Handbook: Achieving Optimal Database Application Performance and Scalability" (Repost)

Performance and scalability are more critical than ever in today’s enterprise database applications, and traditional database tuning isn’t nearly enough to solve the performance problems you are likely to see in those applications. Nowadays, 75-95% of the time it takes to process a data request is typically spent in the database middleware. Today’s worst performance and scalability problems are generally caused by issues with networking, database drivers, the broader software/hardware environment, and inefficient coding of data requests. In The Data Access Handbook, two of the world’s leading experts on database access systematically address these issues, showing how to achieve remarkable improvements in performance of real-world database applications.
