Step 1: Invest in good application design

Nothing has a greater impact on application performance than application design. A poorly designed application will perform badly on the best hardware, and throwing more hardware at a bad design will often result in little application performance improvement.

For instance, during the design and development phases, developers should keep a close eye on the bottlenecks and address the most significant problem areas. During QA, the application should be load-tested using products like
