A few key fundamental concepts overlooked in software application performance and scalability analysis

Software application performance and scalability analysis have become one of the top priorities for large IT firms, but there is a lack of understanding of some of the fundamental concepts among software developers, quality engineers, product managers, and other relevant shareholders.

To fill this gap, in this talk, we discuss some of the essential concepts in performance and scalability testing and studies, including concurrent users, concurrent time intervals, request distributions, load patterns, intrinsic and load scalabilities, effective capacity, etc.

Mastering these basic ideas is crucial for the success of your performance and scalability analysis, capacity optimization, and scalability planning.
