You could implement pagination (using the AsPagination extension method from the MvcContrib.Pagination namespace):

public ActionResult Index()
{
    IEnumerable<MyViewModel> model = ... fetch from somewhere the dataset
    return View(model.AsPagination(1, 10));
}

and in your view:

@model IPagination<MyViewModel>
@(Html
    .Grid<MyViewModel>(Model)
    .Columns(columns =>
    {
        columns.For(x => x.Id);
        columns.For(x => x.Name);
    })
)
@Html.Pager(Model)

The documentation contains examples.

Or do it in Twitter way - get another portion when user scroll to the end of the page.

You can use ajax for loading the data as Dima metioned. If your user experience is extremely important, you may need to load 2 or 3 portions more. For example, the page loads the first two portions, and then loads next two portions when the user scrolls the end of portion 1. This could make the experience more smoother.
