More than one query in a very slow request in the first C#request

Question

I have a method that requests data from the database and in this same method I call another method that also requests the database (mysql).

public class Viagem
{
    public int idViagem { get; set; }
    ...
    public Cidade origem { get; set; } 

public List<Viagem> getViagens(int p)
{
    Connection con = new Connection();
    string query = @"SELECT * FROM viagem"
    if (con.connect())
    {
          using (MySqlCommand cmd = new MySqlCommand(query, con.getConnection()))
          {
              MySqlDataReader reader = cmd.ExecuteReader();

              while (reader.Read())
              {
                  Viagem viagem = new Viagem();
                  Cidade cidade = new Cidade();
                  ...
                  viagem.origem = cidade.getCidade(Convert.toInt32(reader["cidade"]));
              }
     }

}

The getCity method has behavior similar to this getViagens. So when I have nested calls like this is taking too long on the GODADDY server, I have similar codes on other servers the problem does not happen. It’s taking more than 30 seconds for me to return 20 instances.

I need to set up something on the server to make it pooling properly?

Edited: The problem always occurs when I make the first request, the others, even if the values change, occur at an expected time. Any suggestions?

Solved: The godaddy fixes the session time in 5 minutes, disconnecting the non-active users for this time, so the first request always took a long time, the server having to leave the "standby" to only make the request. The solution I will create a task within the hosting itself so that I would request a page every 4 minutes and keep the server "awake".
