Performance Evaluation

Where it Occurs

Why it Matters

Ultimately for one reason, and one reason only,

Relationship between performance evaluation and quality of service (QoS)

Its Goals

It's possible to take this too far. We restrict ourslelves to aspects of performance that are easily quantified, measured and modelled.

Topics in Performance Evaluation

  1. Abstract: based on objectives
  2. Design: what to measure

    Design also applies to simulation and to modelling.

  3. Measure: good measurements produce robust data
  4. Analyse: data requires objective analysis to produce results. Because
  5. Simulate: results require surface explanations
  6. Model: surface explanations sometimes demand deep explanations
