Rather than teaching only one operation, like 'git fetch', how to write down throughput to traces, we can learn about a wide range of user operations that may seem slow by adding tooling to the progress library itself. Operations which display progress are likely to be slow-running and the kind of thing we want to monitor for performance anyways. By showing object counts and data transfer size, we should be able to make some derived measurements to ensure operations are scaling the way we expect.
