In client-server mode, it seems that CPU is going to 100% on the server thread when some client exits without closing its connection. I think, if this is right, that it is a very annoying problem, as this is something that always could happen ...

Daniel Ferreira Jorge: Is db4o reliable to be used in a website with this much concurrent users? Certainly. It's a question of architecture. If you're dealing with a sustained load of > 1 request per second, then you really need to be thinking about what alternatives you can take to make your environment scale by leaps ...

That way we could do a compare on updating and store only the ones that changed. The mechanism could be optimized on a more fine-grained ...
