API非常慢

如何解决API非常慢

我需要从其他网站获取一些详细信息，他们正在提供API。您能帮我建立更快的连接并做出反应吗？我的代码是：

Try
    Dim addr As String
    addr = tb_input.Text

    ' Create a request for the URL. 
    Dim request As WebRequest = WebRequest.Create(addr)
    ' If required by the server,set the credentials.
    request.Credentials = CredentialCache.DefaultCredentials

    ' Get the response.
    Dim response As WebResponse = request.GetResponse()

    ' display the status.
    ' Get the stream containing content returned by the server.
    Dim dataStream As Stream = response.GetResponseStream()

    ' Open the stream using a StreamReader for easy access.
    Dim reader As New StreamReader(dataStream)

    ' Read the content.
    Dim responseFromServer As String = reader.ReadToEnd()

    ' display the content.
    tb_result.Text = responseFromServer

    ' Clean up the streams and the response.
    reader.Close()
    response.Close()
Catch ex As Exception
    MsgBox(ex.InnerException)
End Try
