What is the right way to enable deferRendering in Jquery DataTable

Question

I am looking at improving the performance of JQuery DataTable. I read about deferRendering option. What i understand is when this option is enabled, once TR and TD are drawn, they are retained and need not be drawn again. Please correct my understanding.

some of the examples I have seen they are using deferRender property and some are using bDeferRender property. Which option is correct?

I am showing around 300 records at a time in grid & loading data from server. How can I check if deferRender option is improving performance

Answer 1

It depends on the version of DataTables you are using.

Converting parameter names for 1.10 You could find the two names here.

For checking if it works, simply output something in "createdRow" callback function, so you can count the actual number of created rows.
