Is it more efficient to persist in bulk?

[hrstoyanov]

EmbeddedStorageManager.persist(..) can take several objects . Is it more efficient to persist the entire collection of modified objects (as I suspect) rather than calling persist() for every modified object, one-by-one?

You’re right, in many cases it may be more efficient to use the bulk operations (PersistenceManager.storeAll(Object...)) to store more modified objects at once. The most obvious benefit is that you can reduce the number of required io operations (with the side effect that this will create only one transaction for all objects).
