  • The Business Case for SPE
  • Performance failures negatively impact your bottom line by increasing costs, decreasing revenue or both. This paper shows how performance failures can be cost-effectively prevented. It provides background material on financial analysis techniques and shows how to use them to make your own business case.

    Feel free to use this information to help justify SPE in your organization. If successful, please contact us for assistance on your initial projects to help you achieve quick success. Our approach is unique and has proven successful time after time.

  • Five Steps to Solving Software Performance Problems

    When serious performance problems occur in newly developed software or existing systems with sudden increases in usage, they must be fixed immediately. The project often goes into "crisis mode" in an attempt to tune or even redesign the software to meet performance requirements. In these situations it is vital to maximize the performance and capacity payoff of your tuning effors. This white paper presents a systematic, quantitative approach to performance tuning that helps you quickly find problems, identify potential solutions, and prioritize your efforts to achieve the greatest improvements with the least effort.
