Performance analysis

Description of new feature

Determine the current state of performance of the app.

• How many requests can the app handle at a time? What's the throughput?
• How much resources does the app use under load? How much CPU and RAM would really be needed in a prod instance?

Potential solutions:

• https://www.artillery.io
• https://www.npmjs.com/package/autocannon

Motivation for new feature

• Will the app die under heavy load (e.g. a class)?
• Should we add an explicit queue for upload requests in the Node server so that the underlying web services only handle N concurrent requests?

@mikekucera, you mentioned this last time.

Using something like Netdata might make resource measuring easier. We could refer back to the resource charts after running benchmarks.
