elapsed.yaml

doc: |
  Check out how fast your machine (and Plax) is.

  Publish and receive some messages.  Then emit the elapsed time.

  Example:

    (for I in {1..10}; do
       plax -test demos/example-elapsed.yaml -json 2> /dev/null;
     done) |
    jq -r --slurp 'map(.[1].State.elapsed) | add/length'
