How to manage DOM elements

by

I have implemented Infinite scrolling(i.e Load records when the scrollbar reaches the bottom of the div). It works fine but after loading too many records on the page, the page becomes too heavy & causes slow rendering. Actually, I am using this technique as a replacement of a gridview so, how do i manage heavy DOM in this scenario?
