Memory and network usage soar when scrolling the list quickly; There is no limit on the number of concurrent loads, and there is no operation to cancel the load when the view leaves the visual area.

There is a limit on concurrent downloads at least. Please feel free to improve the performance

The following suggestions

  1. It is recommended to provide the loading thread numerical control system, and it is best to provide a configurable strategy to consume requests in the form of queues

  2. Pending load requests can be cancelled when the view is not visible

  3. Release the cache reference when the view is not visible, so that it can be released in time when there is insufficient memory

  4. Memory caching can support configurable strategies, such as first in first out, setting the maximum number of caches, maximum memory usage, etc

  5. Performance on desktop platforms such as windows should also be considered
