Orthanc Load Test

This is a load test for Orthanc DICOM server. It is based on Locust.

Installation

$ brew install poetry # or pip install poetry
$ poetry install

Refer to Locust Documentation for more details.

Usage

Warning: The load test will create a lot of DICOM instances in the Orthanc server, and also perform delete operations on created instances.

It is recommended to use a separate Orthanc server for testing and not the production one.

Also recommended to upload a few DICOM studies to the Orthanc server before running the load test.

$ # bring up the local services in docker-compose.yml
$ docker compose up -d
$ # run the load test
$ poetry run locust --host=http://orthanc:orthanc@localhost:8042

Then open http://localhost:8089/ in your browser and start a test.

To run headless, in this case, the test will run for 1 minute with 100 users and 10 users spawned per second:

$ poetry run locust --host=http://orthanc:orthanc@localhost:8042 --headless -u 100 -r 10 -t 1m

There is locust-plugins package available, which provides some useful features, such as limit iterations to run 1 task once:

$ poetry run locust --host=http://orthanc:orthanc@localhost:8042 --headless -u 1 -i 1
