This is a comprehensive, practical course that covers the SPE techniques you need to create responsive systems with little or no additional development time or cost.
Questions This Seminar Will Answer
- Precisely, what is Software Performance Engineering (SPE)?
- How is it compatible with other software engineering practices?
- Do you need SPE? How do you convince others?
- What are some useful techniques for building new systems that are responsive to users?
- How can you estimate computer capacity requirements and software response times early in development?
- What are some techniques for creating responsive, scalable software?
- What data is required to accurately predict performance and scalability?
- How do you obtain data for SPE studies, who should do it, and when?
- How do you construct models of software to predict end-to-end system performance – general techniques that may be used with a variety of tools?
- How do you use models to evaluate software requirements, designs, implementations, and computer configurations before implementation and throughout development?
- What is a systematic approach for managing performance?
- How do you measure the performance of software?
- How do you apply these techniques to very large and complex systems?
- What tools support SPE activities ?
- What resources are required and how should SPE be organized and managed?
Many laboratory sessions provide experience with the software performance models.
