Issue with smart rendring with pagination

Hi ,
I am using the dhrmlxgrid have 20 to 60 columns in grid with 85000 rows.I used method enableSmartRendering(true). But the performance is very poor when loading the data.Here I am using pagination. In the first page we have 100 rows., When I move into Second page, then grid is not rendering.

Smart rendering and paging are mutually exclusive functionalities. Paging mode increase loading perfomance itself and there is no any sence use in with Smart Rendering mode. 
If case of 85000 rows loading better to use dynamic paging or smart rendering mode. In dynamic mode only those rows will be loaded from the server side that need to be rendered.
