对服务器端的请求，jQuery Data表非常慢

Question

我在我的网站中使用了jQuery DataTable，显示了我们客户的所有产品列表，我目前正在使用jQuery DataTable插件进行分页，搜索和排序。它工作正常除了一个问题数据加载非常慢。它从sql数据库加载8000行并填充表。

这是我的代码

if($('#product-liste').length) {
    jQuery('#product-list').dataTable({
        "processing": true,
        "serverSide": true,
        "oLanguage": {
            "sSearch": "Search",
            "sProcessing": "Processing...",
            "sLoadingRecords": "Processing...",
            "sLengthMenu": "Show _MENU_ entries",
            "sInfo": "Showing _START_ to _END_ of _TOTAL_ entries",
            "sInfoEmpty": "Showing 0 to 0 of 0 entries",
            "sEmptyTable": "No data available in table",
            "oPaginate": {
                "sFirst": "First",
                "sLast":  "Last",
                "sNext":  "Next",
                "sPrevious": "Previous"
            }
        },
        "ajax": {
            "url": window.location.href,
            "type": "POST"
        },
        "columns": [
            { "data": "id" },
            { "data": "title" },
            { "data": "year" },
            { "data": "type" },
            { "data": "slug" }
        ],
        "order": [[ 0, "desc" ]],
        initComplete: function () {

        }
    });
}
