Descripción
#### Bug, feature request, or proposal:
The mat-table component with selection suffers in performance when the number of elements gets decently large. Selecting a single row or the select all buttons shows a lot of lag that increases as the number of columns increases.
#### What is the expected behavior?
mat-table should be able to support good performance for large number of rows.
#### What is the current behavior?
Slow, laggy animations from clicking on single row checkbox or checkbox for select all
#### What are the steps to reproduce?
Providing a StackBlitz reproduction is the *best* way to share your issue.
https://stackblitz.com/edit/angular-vyv97t
Update table with 100 rows, click a few checkboxes.
Update table with 1,000 rows, click a few checkboxes.
Update table with 10,000 rows, click a few checkboxes.
The performance gets significantly worse.
#### What is the use-case or motivation for changing an existing behavior?
Creating a table which contains lot of entries from the some backend API service. The user should be able to experience smooth UI and user experience.
#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular 6, Material 6.4.7, Chrome
#### Is there anything else we should know?

Línea de trabajo
Comienza con la reproducción vinculada de StackBlitz y compara las interacciones con las casillas de verificación para 100, 1.000 y 10.000 filas, variando el número de columnas. Perfila el comportamiento de selección de mat-table para identificar el origen del retraso. Se considera terminado cuando la selección de filas individuales y de todas las filas sigue respondiendo en tablas grandes.
