SQL CE 3.5 Visual Studio 2008 TOO SLOW

Hi,

I have a desktop application that uses an Access DB.
Now i have converted it to Visual Studio 2008 and tried the SQL CE Edition.
I wrote all the methods, create the database and the tables on the fly and seems to work really fine.
The database is 20MB big, but the performance is vey bad.
I mean with Access it's very fast, you actually don't see how slow it is, and with the SQL CE now,
it takes 7 seconds !!!! for a few access instead of under 1 second with Access.

I can't imagine that this is normal, there must be something i am really missing in my code.
Looks something like this:




Code Snippet
SqlCeEngine engine = new SqlCeEngine("Data Source = URANO.sdf");
engine.CreateDatabase();
engine.Dispose();
// Verbindung öffnen
sqlConnection = new SqlCeConnection("Data Source = URANO.sdf");
sqlConnection.Open();
// creating the tables here with data
sqlCommand = new SqlCeCommand("SELECT ID FROM Laender WHERE Name=@Name", sqlConnection);
sqlCommand.Parameters.Add("@Name", SqlDbType.NVarChar, 30);
sqlCommand.Parameters[0].Value = land;
sqlDataAdapter = new SqlCeDataAdapter(sqlCommand);
sqlDataSet = new DataSet();
sqlDataAdapter.Fill(sqlDataSet, "Laender");
landID = "" + (((int)sqlDataSet.Tables["Laender"].Rows[0][0]) + 1);






this takes 1 - 2 seconds


btw: the whole class is static and the variables also are static.

Would it be better to load all the database tables into datasets, and only work with the datasets in memory ?
Well i thought that the SQL CE Engine, would load the database into memory and be just fast.
I mean we have 2 GB of memory or 1 the most of us, 20MB isn't that much.

Thanks !
