Hi Stackoverflow,

I am executing a simple query against SQL Server 2005:

protected static void InitConnection(IDbCommand cmd) {
        cmd.CommandText = "set transaction isolation level read uncommitted ";
        cmd.ExecuteNonQuery();            
    }

Whenever I profile with dotTrace 3.1, it claims that SNIReadSync method is taking between 100 - 500 ms.

What sort of things do I need to be looking for in order to get this time down?

Thanks!
