It seems like you're interested in the concept of "back pressure," which is not directly mentioned in the provided context from the WWDC sessions. However, if you're looking for information related to performance and memory management, the session titled "Analyze heap memory" might be relevant. This session discusses memory pressure and its effects, such as memory spikes causing system reactions like swapping, compressing memory, and potentially terminating apps.

For more detailed insights, you can refer to the chapter on "Transient memory growth overview" in the Analyze heap memory session. This section might provide useful information on how memory management issues can affect app performance, which could be related to the concept of back pressure in a broader sense.
