We soon(ish) have a setup where we can collect data from WebPageTest keep track of performance. When we got that up and running, we should use one of the free (Nexus 5) instances on WebPageTest.org to run a couple of tests per day. The free one has a limit of 200 tests per day (so we need to decide important pages and number of runs carefully).
What's need to be done to complete the task:
- The https://phabricator.wikimedia.org/T109666 needs to be finished
- Configure it to run with WebPageTest.org API key and URL (I've got the API key)
- The current wptstatsv needs to be updated to add platform/mobile in the key sent to statsv
