SQL Server Connection Pooling

Hello, I have a question about Connection Pooling. I use the following Code on three defferent machines with the same result. No machine has any special configuration. OS is Win XP Pro Sql Server 2005. One Server has Windows 2003 Web Edition with Sql Express 2005.
 1 for(int i=0; i<500;i++) {
3 SqlConnection con = new SqlConnection("Data Source=127.0.0.1\DB;Initial Catalog=Test;User Id=sa;Password=secret;Connection Lifetime=30;Pooling=true;");
4 SqlCommand cmd = new SqlCommand("SELECT TOP 1 * FROM test", con);
5 con.Open();
6 IDataReader reader = cmd.ExecuteReader();
7 reader.Close();
8 con.Close();
9 con.Dispose();
10 }

 When  monitoring  The Counter  logins/sec in Perfmon  logins/sec getsup to 500 per second  when i call this method (everytime!). MSDN says when logins/sec does not stay zero after initial call, pooling does not work. Can you tryy it on your machine an tell me what experience you make? Does Pooling really does not work?
