mat-table laggy behavior with large number of elements

#### 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?

リンクされた StackBlitz の再現手順から始め、列数を変えながら、100 行、1,000 行、10,000 行でのチェックボックス操作を比較します。mat-table の選択動作をプロファイリングして、遅延の原因を特定します。大規模なテーブルで個々の行およびすべての行を選択しても応答性が維持されれば完了です。
