jQuery Grid Plugin - jqGrid

Hi i have two tabs where first tab is my default tab. when i click 2nd tab i load an external jsp page through a script 

$(document).ready(addClickHandlers);

function addClickHandlers() {

$("a.remoteView", this).click(function() {

$("#displayDIV").load("workorder.jsp", addClickHandlers);

});

}

Now the work order jsp file loads a grid data using xml response it gets from a servlet specified in the url:property of jqgrid. Now the problem is the grid take about 20 - 30 seconds to load which i consider is very long. How can i reduce the time it takes to load the grid.

The workorder code is

$(document).ready(function(){

jQuery("#list").jqGrid({

url: '/ams/servlet/getXmlData?q=1',

datatype: "xml",

  colNames:['Complaint No.','Apt. No.', 'Name', 'C_Nature','C_Desc','Phone','E-Mail','Status','Regd. On','Regd. By'],

  colModel:[

    {name:'cno',index:'1',width:130,editable:true,editoptions:{readonly:true}},

    {name:'ano',index:'2',width:100,editable:true,editoptions:{readonly:true}},

    {name:'name',index:'3',width:100,editable:true,editoptions:{readonly:true}},

    {name:'cn',index:'4',width:100,editable:true,editoptions:{readonly:true}},

    {name:'cd',index:'5',width:100,sortable:false,editable:true,edittype:"textarea", editoptions:{rows:"10",cols:"50"}},

    {name:'ph',index:'6',width:100,editable:true,editoptions:{readonly:true}},

    {name:'mail',index:'7',width:100,sortable:false,editable:true,editoptions:{readonly:true}},

  {name:'states',index:'8',width:100,editable:true,edittype:"select",editoptions:{value:"open:Open;close:Closed"}},

  {name:'ron',index:'9',width:100,editable:true,editoptions:{readonly:true}},

  {name:'rby',index:'10',width:100,editable:true,editoptions:{readonly:true}},

  ],

rowNum:10,

autowidth: true,

rowList:[10,20,30],

pager: jQuery('#display'),

sortname: '1',

viewrecords: true,

sortorder: "desc",

loadonce: true,

caption: "Work Order"

  });

});
