Measurements of how hosting, video and scheduled tasks behave, each with its method and the scripts to repeat it.

• Files in an in-memory /tmp count against a container's memory limit

  A program killed with free space left. We measured tmpfs writes in memory-limited containers, with scripts to repeat it.

• Where the MP4 index sits, and what it does to playback

  Same video, index at the start or the end. We timed first frames in Chromium, with and without range requests.

• How late do scheduled tasks run when visitors trigger them?

  WordPress runs scheduled tasks only when someone visits. We measured how late they run at six traffic levels.
