Summary

In order to compare upcoming changes for their effectivness, measure
performance by counting opertions and the runtime of each operation over the time. Accumulate all tests in a single instance, so make it complicated over the time. If you wait long enough, you will notice the expiry of old flows.

Test Plan

Run the test for 15 seconds, while applying multiple rounds of:

  • try to generate 15000 valid connections
  • let 2000 random external sources ask for random ports
  • let a single random external source hammer with 1500 identical packets
  • try to respond to the valid connections in a random order
$ perf 15 15000 2000 1500
