More performative way to return data to View

In a view where we return a list of objects, and we need to demonstrate the quantity, such as a small report, using some conditions.

What is the most performative way to return data to view ?

Explaining better.

When we return an object list to view , for example:

Using the Microsoft example , we have:

public class Movie 
{ 
    public int ID { get; set; } 
    public string Title { get; set; } 
    public DateTime ReleaseDate { get; set; } 
    public string Genre { get; set; } 
    public decimal Price { get; set; } 
} 

And we return all Movies registered in our controller , for example:

public ActionResult Index() 
        { 
            return View(db.Movies.ToList()); 
        } 

In this case, let's say we want to know the amount of movies and show in a table, we could bring in a ViewBag like this:

  public ActionResult Index() 
        { 
            var filmes = db.Movies.ToList();
            ViewBag.TotoalFilmes = filmes.Count();
            return View(filmes); 
        }  

And in view only show ViewBag , like this:

<p> Total: @ViewBag.TotalFilmes</p>

This is one way to do it, but another would be simply using Count() directly in view , like this:

<p> Total: @Model.Count</p>

Here's my question: Which of the two forms is "better" (more performative)?

Remembering that in the example I just showed with a ViewBag . But I wonder if we have a lot of data.

If you have a third way, which is better, I'll be happy to get to know you too.
