Elixir vs Go Performance (Anton Putra)

  1. Only p90 is being tested/shown - way to low.
  2. A custom simple thrown together client is being used - most likely doing CO(Coordinated Omission) - eg. results are incorrect/misleading
  3. One system is mostly tested in overload >100% cpu (due to 1&2 nothing is really measured before overload occurs eg. latency 0?! ), the test is quickly stopped once the Go test reaches overload.
  4. The tests are out of sync, one test gets ahead of the other, for a given time.

Remedy:

  1. Use p99, or better measure the distribution.
  2. Use a proper client like Gatling (it even has an easy to use/install javascript tool these days: https://docs.gatling.io/tutorials/test-as-code/javascript/running-your-first-simulation/)
  3. Keep going into overload, for both systems.
  4. Solved by 2 - using a proper client.

So it’s all about using a proper load testing tool/client.
