9.4 Conclusion
In this chapter, we have discussed the general benchmarking methodology and key considerations for benchmarking Web applications and WebSphere Commerce with DynaCache specifically. Although there is no hard and fast rule for planning, designing, or obtaining a benchmark, we have attempted to provide enough guidance to make the task practicable. A benchmark is grounded in business requirements and can be used for both current and future, ongoing, evaluation of system performance. It is our sincere conviction that every site should have a benchmark.
In the final section of the chapter, we have also given an example of benchmarking WebSphere Commerce with DynaCache. As our tests have shown, the use of DynaCache in WebSphere Commerce systems is not merely an option, but an imperative. Well-defined and customized dynamic caching can improve system performance ten- or even a hundred-fold, helping us shorten response times, increase workload, get the most out of the hardware we have, and inform us where best to spend our hardware budget to improve performance or support more customers as the popularity of our Web site grows.
