Virtual Vertical Grouping
The Vertical Virtualization optimizes the views' rendering by doing a DOM virtualization. It is supported only for Day, Week, WorkWeek and Month views.
You can enable it by using the Virtual(true) method in the view configuration
views.WeekView(view => view.Selected(true).Virtual(true));.
When enabled the view will render additional DOM elements as you scroll down.
