我创建了一个服务器监控工具。现在应用程序的性能非常慢。显示18台服务器的服务器状态需要6分钟，但我需要让应用程序更快..任何人都可以帮我多线程下面提到的代码。代码中没有错误。它工作正常，但我需要让它更快..
以下是代码： -

{
public partial class Form1 : Form
{
DataTable dt;
string accessconn = ConfigurationManager.ConnectionStrings["accessconn"].ConnectionString;

//public string MyValueapp
//{
// get { return app.Text; }
//}
//public string MyValueip
//{
// get { return ip.Text; }
//}
public Form1()
{
InitializeComponent();
//app.Text = frm2.MyValueapp;
//ip.Text = frm2.MyValueip;
}
//public Form1(string appName, string ipAddress)
//{
// InitializeComponent();
// app.Text = appName;
// ip.Text = ipAddress;
//}
