DragRace

DragRace (called DragRaceiOS in the filesystem) is an InternalUI app which is used to run various speed tests on a given network. Within the app, there are options for both Download Size and Upload Size, those being 1MB, 5MB, 50MB, or 100MB. There is also a switch to enable graphing, which will show you the ping, download speed, and upload speed as the test is in progress. Under the graph, more detailed information from each category is provided. DragRace was phased out in the 14.0 InternalUI build. Although it still appeared as DragRaceiOS in the filesystem, it shows up on the Home Screen as Speed and has a completely redesigned app icon and UI.
