What to measure about performance

People usually think about performance wrong, resulting in asking wrong questions like can your server handle 10K connections or 2000000 users?.

What is important to remember: Performance is a multidimensional characteristics. its impossible to make a picture of the system performance using only 1 metric.

When you asked about how good some stream of something is performing, you should think about:

  • Throughput, Bandwidth
  • Latency
  • Response time
  • Footprint

The relation between throughput and latency is described by Little’s law.
