Hi Atiraj,

Thank you for the runnable example.

There are certain browser- and system-specific limitations, regarding the number of rows/items that can be rendered simultaneously in the Grid, beyond our control.

The Angular framework also imposes some performance penalties.

The most straight-forward options for improving the performance and rendering times of the Grid, are to enable production mode (Angular - related):

https://angular.io/guide/deployment#enable-prod-mode

... and to utilize either the paging or virtual scrolling functionalities of the Grid (Kendo UI - related):

In the discussed scenario, filtering itself does not take long, but rendering all resulting rows is time and resource-consuming.

Performance can be significantly optimized via the approaches, suggested above. Here is an updated version of the plunker with enabled production mode and paging:

I hope this helps.
