large data sets

To optimize mobile app performance for handling large data sets or database queries, there are several steps you can take. First, you should minimize the amount of data transferred between the app and the server by using efficient data retrieval techniques like pagination or lazy loading. Additionally, you can optimize your database structure by using appropriate indexes and creating efficient queries. Caching data on the device can also greatly improve performance. Finally, consider optimizing your code by using asynchronous operations, reducing network requests, and optimizing memory usage.
