As an admin, it takes 33 seconds and 1MB. The feed-shelf-mine endpoint: 1. Fetches all shelves rather than just the currently active carrier/region combo the user is browsing. 2. Fully deserializes all apps. This could be sped up by only fetching what we need since we know which carrier/region the user is looking at, and swapping out the app serializer for something slimmer.
