Improving Entity Framework Performance during testing

I'm trying to reduce the startup time for tests against an EF 6x datastore. The tests are within a transaction and the db gets rolled back once done. I would appreciate any suggestions on how to retain an instance of the DbContext between test sessions so that EF doesn't have to go through the whole view generation process again?

I don't want to use mocks/fakes, non-Microsoft branch of EF and interactive views are already in place. Thank you.
