This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI. To prepare ourselves for a big change in the tech stack of our endpoint, we decided to track metrics around the time taken to respond to queries.

However, one metric I feel that front-end developers overlook all too quickly is Time to First Byte (TTFB). A lot of people surmise that TTFB is merely time spent on the server, but that is only a small fraction of the true extent of things. The reason is because mobile networks are, as a rule, high latency connections.
