One point can be singled out as being dominant: the failure to deal with software performance requirements right from the start of projects.
The objectives of this chapter are to show:
- Why it is important to design for performance in real-time systems
- Where performance requirements come from
- How software performance relates to system performance
- How performance targets get translated into performance achievables and deliverables
- Why modeling and simulation are key techniques ...
