Srinath, Cary's reference #5 is most likely what you are looking for. Learn more about Neil Gunther's "Universal Scalability Model" in his book "Guerrilla Capacity Planning". Kurt

Hi Cary,

Great article. Do you think it is practical/ possible the performance of a server via a equation? It will not be perfect, but still will help us to understand what it does. For example, I tried to draw the performance graph's some time bach throughput vs. concurrency and latency vs. concurrency http://srinathsview.blogspot.com/2012/05/how-to-measure-performance-of-server.html. Potentially, one can try to match a mathematical formula to the figure.
