Do these references point to the same object instances, or are these copied as well?
They are independant copies
Why exactly is this? concurrency issues?
Yes.
Is there a way to optimize this?
1. Obviously, use fewer threads. Do you have a component that otherwise benefits from many threads? 2. If you have large immutable state that does not hold references to persistent objects, use application-specific code to share this state between threads.
I assume it's an issue on the ZODB level?
