Performance is a feature.

It can sometimes difficult to talk about performance when one technique improves throughput but decreases response time.

Vehicle Time to Paris Speed Passengers Throughput (pk/h)
Ferrari 2 hours 250 km/h 2 500
Greyhound 5 hours 100 km/h 60 6000

Is throughput in real system just an inverse-time metric. ???

3 - Gain

The bucket list of performance gains:

  • don’t do it

  • do it less often
  • do it more efficiently

  • do less wasted work
  • or spend less time waiting.
