• this.store.find('modelType'); always hits the server, because no ID is given, and there may be new records on the server. Use find in the application route, and all in other places to avoid polling the server every time.
• this.store.find('modelType', model_id); only hits the server if the model with the given type and ID is not already in the cache.
