weird prob with pagination

here a link of the screenshot http://oi39.tinypic.com/5b9ph4.jpg

there's a 43k item in the database, it getting slow because there's too much button here the code

	$('.datatable').dataTable({
		'bLengthChange': true,
		'bPaginate': true,
		'sPaginationType': 'full_numbers',
		'iDisplayLength': 5,
		'bInfo': false,
		'oLanguage':
		{
			"sLengthMenu": "Show_MENU_ items per page",
			'sSearch': 'Search:',
			'oPaginate':
			{
				'sNext': '>',
				'sLast': '>>',
				'sFirst': '<<',
				'sPrevious': '<'
			}
		}
	});

any clue what's wrong ?
