# load-testing-utils / content-review ## How to Run `docker compose up --scale worker=8` Note (https://docs.locust.io/en/2.2.3/running-locust-distributed.html): Because Python cannot fully utilize more than one core per process (see GIL), you should typically run one worker instance per processor core on the worker machines in order to utilize all their computing power. ## Example Run ### Terminal I chose to create 8 workers as my macbook has 8 processor cores. ```shell (load-testing-utils)  py[load-testing-utils-nv6180MI]  ~/p/l/content-review   PEACE-126_add_content-review_load_tests  docker compose up --scale worker=8 [+] Running 9/9 ⠿ Container content-review-worker-1 Recreated 1.9s ⠿ Container content-review-master-1 Recreated 2.2s ⠿ Container content-review-worker-6 Recreated 2.0s ⠿ Container content-review-worker-2 Recreated 1.9s ⠿ Container content-review-worker-7 Recreated 2.1s ⠿ Container content-review-worker-4 Recreated 1.9s ⠿ Container content-review-worker-8 Recreated 1.7s ⠿ Container content-review-worker-5 Recreated 2.1s ⠿ Container content-review-worker-3 Recreated 2.0s Attaching to content-review-master-1, content-review-worker-1, content-review-worker-2, content-review-worker-3, content-review-worker-4, content-review-worker-5, content-review-worker-6, content-review-worker-7, content-review-worker-8 content-review-worker-7 | [2022-02-18 22:37:32,260] f41089931290/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-4 | [2022-02-18 22:37:32,462] 19e8f8b91016/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-5 | [2022-02-18 22:37:32,691] 1aedf8ac62ad/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-3 | [2022-02-18 22:37:33,430] d1fa79f04950/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-6 | [2022-02-18 22:37:33,822] 29478e5d54e9/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-1 | [2022-02-18 22:37:34,607] 63a7a1a3eede/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-2 | [2022-02-18 22:37:34,840] 7658833ff7eb/INFO/locust.main: Starting Locust 2.8.2 content-review-worker-8 | [2022-02-18 22:37:35,331] 17e601d1503f/INFO/locust.main: Starting Locust 2.8.2 content-review-master-1 | [2022-02-18 22:37:35,784] e7ca10fd3695/INFO/locust.main: Starting web interface at http://0.0.0.0:8089 (accepting connections from all network interfaces) content-review-master-1 | [2022-02-18 22:37:35,870] e7ca10fd3695/INFO/locust.main: Starting Locust 2.8.2 content-review-master-1 | [2022-02-18 22:37:35,876] e7ca10fd3695/INFO/locust.runners: Client 'd1fa79f04950_2f4af5d106384a469ba4cb4e0fe7da7d' reported as ready.
