Page Unresponsive is showing, while rendering >1000 rows of records in a single page (chrome and Mozilla.)

I have >1000 (1099) records in my domain objects which I fetched through AJAX from web service in JSON Format. I want to show all the records(>1000) in single page using scroll bar.

while loading the (>1000) records through Handlebars, Browser is showing Page Unresponsive message(Both Chrome & Mozilla).

Technology Stack : Spring Boot, Ember Js, Handlebar.Js

Your assistance in this is greatly appreciated. Thanks.
