I am working on RealityKit app project and I have a question. when viewing a 3d model it takes more than one minute to show up, the app loads the models from firebase fast but it takes time to show on the screen and I am using iPad 7 generation to run the app. I tried obj and usdz format and there is no difference

This is the code I use

func View3DObject( Name : String){
        
        //start of bring models from firebase
        @ObservedObject var model = Model(name: Name, category: .animals)
        
        //set object on floor
        let anchorEntity = AnchorEntity(plane: .any, classification: .floor)
           
        
        //get object from database
           let resultModel = model.asyncLoadModelEntity(){ result in
            
               
        //enable intraction and movment
            result.generateCollisionShapes(recursive: true)
               self.arView.installGestures([.translation, .rotation, .scale],for: result)
   
            
            anchorEntity.addChild(result)
               
      

        }
        
        
        //add object to secne
            self.arView.scene.anchors.append(anchorEntity)
            print("Model is added to the scene" )


    }
    
}

asyncLoadModelEntity function:

 func asyncLoadModelEntity(completion: @escaping (_ result: ModelEntity) -> Void) -> ModelEntity{
        var result = ModelEntity()
        FirebaseStorageHelper.asyncDownloadFilesystem(relativePath: "models/\(self.name).obj") { localUrl in
            self.cancellable = ModelEntity.loadModelAsync(contentsOf: localUrl)
                .sink(receiveCompletion: { loadCompletion in
               
                    switch loadCompletion{
                    case .failure(let error): print("Unable to load modelEntity for \(self.name). Error: \(error.localizedDescription)")
                case .finished:
                    break
                }
            }, receiveValue:{ modelEntity in
                result = modelEntity
                self.modelEntity = modelEntity

                // self.modelEntity?.scale *= self.scaleCompensation
                print("modelEntity for \(self.name) has been loaded")
                completion(result)
            })
        }
        return result
    }

And this is the console
