title: Performance Issue for the Angular Mat-Table
body: <p>I have a mat-table which load data from JSON file. If I load 100 rows then the site becomes slow and it takes 1 min to load the table.</p>
  
  <p>From the browser performance, I got to know, <code>ZoneDelegate.invokeTask</code> is triggered and continue checking recursively. everywhere it is <code>callViewAction</code>. </p>
  
  <p>What would be the solution to this issue?     </p>
