.Connection.Open() takes about 5 seconds to execute.  Not sure why.

I am using SQL Server Express 2005 and my SQL statement is small(under 5 fields).

My SQL Server is local, but i have tested on a network SQL Server and it takes just as long.  I would have thought this would be almost instant.

Because of the time issue it inturn makes my website run sluggish.

Am I better off using OLEDB? Or does it not matter. (see code below)

My IIS is 6.0
I am running.Net 2.0/3.5
Coding in VS 2008

Could it be something in my web.config?
my connection string
"UID=MySite;PWD=MySite;server=WORK5\SQLEXPRESS;database=MySite;"
 
 
    Public Shared Function GetDataReader(ByVal SQLStatement As String, ByVal ConnectionString As String) As SqlDataReader
 
        Dim dr As SqlDataReader
        Dim cmd As New SqlCommand()
 
        With cmd
            .Connection = New SqlConnection(ConnectionString)
            .Connection.Open()
 
            .CommandText = SQLStatement
            dr = .ExecuteReader(CommandBehavior.CloseConnection)
        End With
 
        Return dr
    End Function

>>Am I better off using OLEDB?

No, the SqlConnection will give you better performance than the OleDBConnection.

If you go out to a command prompt and PING WORKS5, how quickly do you get a response?  I'm wondering about a name resolution problem.

OK, it seems that the SQL Server Express is going to sleep. Related links:

pardon my ignorance, but I am fairly new to SQL Server (formly a Access guy) where in SQL can I find the Auto Close /Sleep setting?

That makes sense...b/c it funs like crap the first time, then it is blazing fast after that.  Then if i log in 5 min later it is slow again.

When i open SQL Management Studio
and I right my Database and goto Properties
I see an "Auto Close" setting set to True  is that what I am looking for?

or is it a global SQL setting not a Database specific setting?
