What if you had all the data you needed to measure system performance and scalability at any tier, discover performance and stability problems before they happen, and plan for capacity and performance by modeling the system's behavior at greater load than you currently have? Now it is as easy as running tcpdump and processing the result with a tool. In this two-part discussion you will first learn how to do black-box performance analysis to discover hidden problems in your systems. In the second part you will learn about mathematical performance and scalability models, how the inputs can be computed from TCP packet headers, and how to derive and interpret the results with free tools from Percona Toolkit.
