db4o supports callback-methods on each class. In order to support this, db4o scans all persistent classes and looks for the callback-method signature. When a lot of different classes are stored, this may take some time, especially on embedded devices. Therefore you can disable the object callbacks, when you don't need them.
Note that this doesn't disable the global events. These can still be used, even when callbacks are disabled.
IEmbeddedConfiguration configuration = Db4oEmbedded.NewConfiguration(); configuration.Common.Callbacks = false;
Dim configuration As IEmbeddedConfiguration = Db4oEmbedded.NewConfiguration() configuration.Common.Callbacks = False
