Studio – Playback Performance
Display playback and data-streaming performance statistics. Displayed only when the experimental feature for "Studio Debug Panels" is toggled on in the app's settings.
The following statistics are displayed for a given playback session. "Instantaneous" statistics are reported based on the most recent frame, and also are averaged over the last 5 seconds.
The player tries to play at the speed specified by the user, but may not be able to keep up, given heavy layouts and large amounts of data. This chart displays the actual playback speed as a ratio of bag time to playback time.
The number of frames played per second. Though the player can play back at up to 60fps, this statistic will be lower if frames take longer than 16ms to render.
Bag frame time
The duration in bag-time for the rendered frames in milliseconds. To "keep up" with playback, Studio will often emit "larger" frames.
The amount of data received by the player in megabits per second. For remote bags, this includes topics that the player is not subscribed to. This statistic does not account for Content-Encoding compression, so it may be larger than the actual network bandwidth.
