Try it in 30 seconds

Start the server with the image or with the binary (see Install if you have neither yet):

docker run --name torchio -p 3000:3000 altrdev/torchio    # with Docker
torchio serve                                             # with the binary

torchio with no command does the same as torchio serve: it is what the Docker image runs. The server stays in the foreground, so Ctrl+C stops it; use a second terminal tab for torchio watch.

In a second terminal, watch what it does:

docker exec -it torchio torchio watch    # with Docker
torchio watch                            # on your local machine, press m to start a memory test

In a third one, put it under load, and see the bars move:

torchio memory 200 --hold 20
torchio disk 100 --hold 20
torchio stress 44

The same thing with curl: curl "http://127.0.0.1:3000/memory?mb=200&hold=20". See Starting a test.
