DataTable：如何加快页面加载？

Question

I have about 20,000 rows in my database, and I use DataTable to load all of those data.

• DataTable is loading all of my data at the beginning.
• DataTable works fine with a small amount of data like 100 or below, but in my case, my page took about 3 minutes to load a page. Very Bad !

What is the most efficient way to improve the loading speed using DataTable ?

Update:

Here is my table

<table id="inventory_exact"> ...

Here is my setting to it

  // Setting to Inventory Table 
  $('#inventory_exact').dataTable({

    "lengthMenu": [ 10 ] ,
    "bLengthChange": false,
    "searchHighlight": true,
    "bInfo" : false

  });

Update 2: - server side

@niyou : I use PHP Laravel , so I query my data and display them by doing this

            @foreach ( Inventory::all() as $inventory)
             <tr>
                <td>{{ $inventory->sku }} </td>
                <td>{{ $inventory->description }} </td>
                <td>${{ $inventory->price }} </td>
                <td>{{ $inventory->stock }} </td>
             </tr>
            @endforeach

Answer 1

When you are dealing with client-side large datasets (by large i define as over 1000) , you would probably want to switch to the Server-side implementation of data for your datatables data

Using the newest 1.10 syntax it would look like this

table = $('#example').DataTable( {
    serverSide: true,
    ajax: {
      url:"index.cfm/observers/json",
      },
  });

where the url returns a json object that has draw, totalrecordcount, totalfilteredcount, and data

I have included links to documentation for
