AJAX 响应很慢

Question

I am working on PHP CodeIgniter. By clicking on customer name I call a JavaScript function customerBasic for some other purpose that also call show_cs_info that send AJAX call to controller as below.

AJAX function:

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 function:

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);
     }
});
}

controller

 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);
 }

Model

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

The AJAX call is taking 1.05s. How can I make it faster?

Answer 1

实际上，如果数据库服务器在另一台服务器上，您需要检查网络连接并尝试消除网络延迟..... 在其他情况下，如果您在本地服务器上工作并且在同一台机器上有 web 和数据库服务器，然后检查 CPU 使用率和MySQL 上的工作负载可能因某些查询而卡住……进一步升级您的服务器和 MySQL 版本等……

You are executing an ajax post request without any data. Post requests are intended to cause a server reaction and thus are slower. So setting type to 'get' will speed up your request somewhat.
