ODBC Connection Pooling not working with 10g On Windows 2003

Question

I have a bog standard Windows 2003 machine and installed Oracle 10g on it. It seems that the ODBC Connection pooling is not working.
I am using ASP and every time I try and render a simple page it is taking 4-5 seconds which is the time necessaru to create a database connection. ( Machine is 2.8 Ghz Xeon with 2 gigs of Ram)
The following VB Code can be used to test that the pooling is not working. It creates 2 connections to the database. On oracle 10g on windows 2003, it takes 5 seconds to create the first connection, and another 5 seconds to create the second connection.
When you run the same program on windows 2000 and oracle 9, the first connection take 3 seconds, and the second 0.05 seconds. ( The shorter time being due to the connection pooling)
time1=timer()
set conn=createobject("adodb.connection")
Conn.Open "dsn=oracleDSN;uid=yourusername;pwd=yourpassword"
time2=timer()
msgbox time2-time1
conn.close
set conn=nothing
time1=timer()
set conn=createobject("adodb.connection")
Conn.Open "dsn=oracleDSN;uid=yourusername;pwd=yourpassword"
time2=timer()
msgbox time2-time1
conn.close

ODBC Connection Pooling is controlled by the ODBC Driver Manager and defaults to off for every driver on every platform. Have you enabled connection pooling for your driver in the ODBC Data Source Administrator?
