Creating and adding many MapPins at once, either to a MapPinLayer or as children of the MapRenderer, could be time consuming and thus cause a frame hitch. If the MapPins can be initialized and added all at startup, this may be an acceptable one time hit. However, if data is being streamed and converted to MapPins throughout the app's lifetime, consider spreading out the MapPin creation and addition over multiple frames, i.e. time slice the additions. This will help to maintain render performance. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://www.xrdev.app/mixed-reality-docs/lessons/lesson-5/what-could-go-wrong/can-adding-pins-would-slow-down-my-application.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
