Speeding up datatables when retrieving data from indexedDB

I am using datatablejs on client side for displaying the database to client. I download the database from server initially using backbone indexeddb adapter and store it in indexedDB so as to support offline access to data. However, datatables take approx around 5 minutes to render 20,000 entries from indexedDB. This is my JS code:

I have tried using methods listed here: http://datatables.net/faqs#speed but none of them works. I have also tried using infinite scrolling. It doesn't reduce time. Can anybody suggest a way to make the list page load faster?
