Cache references to avoid the expensive calls especially in the update function. This can be done by caching these references on start if available or when available and checking for null/bool flat to avoid getting the reference again. Examples: Cache component references change void Update() {...

The Lru Cache will store all the added resources (values) for fast access until it reaches a memory limit, in which case it will drop the less used resource (value) to store the new one. To initialise the Lru cache you need to provide a maximum memory value. This value depends on your application r...

To add a resource to the cache you must provide a key and the resource. First make sure that the value is not in the cache already public void addResourceToMemoryCache(String key, Bitmap resource) { if (memoryCache.get(key) == null) memoryCache.put(key, resource); }

To get a resource from the cache simply pass the key of your resource (String in this example) public Bitmap getResourceFromMemoryCache(String key) { memoryCache.get(key); }

This approach will generate one table on the database to represent all the inheritance structure. Example: public abstract class Person { public int Id { get; set; } public string Name { get; set; } public DateTime BirthDate { get; set; } } public class Employee : Person { ...
