我正在开发PHP CodeIgniter。通过点击客户名称，我调用了一个JavaScript函数customerBasic，用于其他一些目的，也调用了show_cs_info，将 AJAX 调用发送到控制器，如下所示。
AJAX 函数：

function customerBasic(customer_id,isConsumer, name )
 {
   document.getElementById('random').value = customer_id+"/"+name;
   $.ajax({
        url: site_url+"customer/connections/index/"+customer_id+"/"+0+"/"+isConsumer,
        type: 'post',
        success: function(data)
        { 

           show_cs_info(customer_id);
        }
     });

}

show_cs_info函数：

function show_cs_info(id)
{
  $.ajax({
     url:site_url+"customer/customer/show_cs_info"+"/"+id+"/"+'no',
     type:'post',
     success:function(data)
     {
        $('#right_div').html(data);
     }
});
}

控制器

public function show_cs_info($id, $bit)
 {
    $id = urldecode($id);
    $bit = urldecode($bit);
    $this->load->model('customer_model');
    $data['val']= $this->customer_model->show_cs_info($id);
    $this->load->view('show_cust_info_view',$data);
 }

型号

public function show_cs_info($id)
 {
        $this->db->where('customer_id',$id);
        $result = $this->db->get('customer_info');
        return $result->result();
 }

AJAX 调用需要1.05秒。我如何才能使它更快？
