mysql 连接很慢怎么处理，请大家支招

大家好 购买的是阿里云mysql数据库！
开发环境： VB6
mysql驱动版本：5.1
连接代码如下：(安全考虑，部分用*号代替)

Public Sub Open_mysqlDataBase()
On Error GoTo Err_Pro
    Dim T
    Sys_Path = "12*.27.***"
    Sys_User = "root"
    Sys_PSWD = "******"
    Sys_DATA = "ordercon****"
    sConnStr = "DRIVER={MySQL ODBC 5.1 Driver};" & _
         "SERVER=" & Sys_Path & ";" & _
         "DATABASE=" & Sys_DATA & ";" & _
         "UID=" & Sys_User & ";PWD=" & Sys_PSWD & ";" & _
         "OPTION=3;stmt=SET NAMES GB2312"
    With CNN
        .CommandTimeout = 20
        .ConnectionString = sConnStr
         T = Timer
        .Open
         MsgBox Timer - T & " 秒"
    End With
    Exit Sub
Err_Pro:
    MsgBox "服务器/数据库连接失败！请联系管理员处理！" & Chr(10) & "错误代码：" & Err.Number & "." & Err.Description, 48, "提示"
End Sub



运行结果：用时 1.65秒
请问是什么原因了？
