It's been that way since MDAC 2.1. And as John states, with a few tweaks it can run even faster.

Set the cursorlocation property of the connection to adUseClient and execute the SQL with the connection's Execute:

oRS = oConn.Execute("Select * From patledger")

And if this is to a SQL Server make sure you are using the OLEDB provider instead of a DSN as in your example.
