Initializing the datatable before filtering

wns

I connected my system with database consists of millions of data. However, the system keeps lagging once connecting. So, I plan to use the serverside processing to initialize the table to empty table so it no need to process all the data in a time (and lag). Not sure if it's a good way to deal the heavy data with the datatable. Here is my what I tried but it didnt work,

<script type="text/javascript">
  $(document).ready(function(){

      fill_datatable();

      function fill_datatable(age = '', age2 ='' ,dataGender = '') 
    {
        var dataTable = $('#table_data').DataTable({
            processing: true,
            serverSide: true,
           " iTotalRecords": 57,
          "iTotalDisplayRecords": 57,
    },
