Performance, Metrics and Parameters
- Performance:
- How fast does computer A run MY program ?
- Is machine A generally faster than machine B, and if so, how much faster ?
- Parameters: clock rate, poisson inter-arrivals ...
- Metrics: throughput, response time, queue length ...
- Metric should characterize the design tradeoffs adequately
- Metrics are usually functions of many factors. Use of one factor alone may be misleading.
