bServerSide on server side

I have a table with 150 columns and 400+ records.
when I load with dataTable it actually hang. I intend to use bServerSide so it will do all the process at server side.


$('#mainTable').dataTable( {
"bDestroy": true,
"bRetrieve": true,
"bSortClasses": false,
"iDeferLoading": 57 ,
"bProcessing": true,
"bServerSide": true,
"sAjaxSource": "table.html",
"fnServerData": function ( sSource, aoData, fnCallback ) {
$.ajax( {
"dataType": 'json',
"type": "POST",
"url": sSource,
"data": aoData,
"success": fnCallback
} );
}
} );

With only oracle and php generated HTML table, am I able to get bServerSide moving?
How to make it work?
