Page Load Time and the YSlow scalability model of web application performance

This is the first of a new series of blog posts where I intend to drill into an example of a scalability model that has been particularly influential. (I discussed the role of scalability models in performance engineering in an earlier blog post.) This is the model of web application… Continue reading

The Role of Scalability Models in Performance Testing

Performance testing is one of the most important practices associated with applying software performance engineering principles to acceptance testing and other quality assurance processes. This blog entry discusses the key role scalability models play in performance testing. A scalability model hypothesizes a relationship between a performance-oriented response time or throughput… Continue reading
