Keep in mind that ADO is dog slow. Use OLEDB directly and you will see 2-3 times perfomance increase. Example: I created an ASP page that used ADO to return a simple recordset(SELECT TOP 50 FROM TABLE1) and loop through the recordset to generate an HTML table. Then I wrote a C++ COM object that that accessed OLEDB directly instead of ADO from my ASP page. Then I used ATL Server and my C++ COM object.

Here's what I found:
1) ASP/ADO - 70 requests/sec
2) ASP/C++ COM/OLEDB - 290 request/sec
3) ATL Server/C++ COM/OLEDB - 370 request/sec.

The problem with ADO is that everything is a VARIANT so it can be easily used by scripting clients. OLEDB is meant to be used by compiled/early bound languages.
