    public abstract class JournalPerfSpec
    extends JournalSpec
    This spec measures execution times of the basic operations that an PersistentActor provides, using the provided Journal (plugin).

    It is *NOT* meant to be a comprehensive benchmark, but rather aims to help plugin developers to easily determine if their plugin's performance is roughly as expected. It also validates the plugin still works under "more messages" scenarios.

    In case your journal plugin needs some kind of setup or teardown, override the beforeAll or afterAll methods (don't forget to call super in your overridden methods).

    For a Java and JUnit consumable version of the TCK please refer to JavaJournalPerfSpec.
