The Growth-Team intends to build the MediaWiki-extensions-ImpactModule using primarily AQS queries (see the review at T433352). To ensure that is indeed viable, we should measure how long all relevant queries take to respond (warning: this might change when T433983 finishes, but not substantially). This applies even with caching – whenever the cache is cold, the AQS queries would be made on the fly.

Within this task, we should write a maintenance script that downloads relevant data from the AQS, and checks how long it takes. Then, we should decide if such a delay is acceptable or whether we need to take some precautions to ensure the cache is not cold in most cases.

Note we should run the measurement in production (in practice, the requests would be done within the DC rather than across half of the world).
