I tested, the performance is worse than ODP.NET unmanaged driver when use regular ADO.net API,
Entity Framwork 4.3 (code first) code seems can work using ODP.NET unmanaged driver, but totally
not work under this beta ODP.NET managed driver.

Performance is one of the key areas ODP.NET, Managed Driver will address by the production time frame. The first beta release is intended to provide the features and APIs that most ODP.NET developers use.
