MySQL的淨連接池connection.Open（）很慢

版本6.4.4：MySQL的淨連接池connection.Open（）很慢

使用的MySqlConnection的最基本的實現，下面的代碼預裝連接池到達時，需要每個連接2-5秒在我的連接字符串中配置「最小池大小」。

任何想法爲什麼需要這麼長時間，如何解決或變通方法？

連接字符串：

<add name="users" connectionString="server=192.168.1.2;User Id=dbuser;password=dbpassword;database=users;Pooling=true;Min Pool Size=10;Max Pool Size=50;Persist Security Info=True;" />

代碼

private static void MySqlConnectionTester() 
{ 
    string connectionString = ConfigurationManager.ConnectionStrings["users"].ConnectionString; 

    using (var connection = new MySqlConnection(connectionString)) 
    { 
     using (var command = connection.CreateCommand()) 
     { 
      command.CommandText = "select * from users;"; 

      try 
      { 
       connection.Open(); // This line hangs until "Min Pool Size" is reached. 
       using (var reader = command.ExecuteReader()) 
       { 
        while(reader.Read()) 
        { 
         // Read results 
        } 
       } 
      } 
      catch(Exception ex) 
      { 
       // Log exception 
      } 
      finally 
      { 
       connection.Close(); 
      } 

     } 
    } 
}
