Dynamic weaving is used for several performance enhancing features in EclipseLink. (e.g. lazy loading of ToOne relationships, fetch groups, optimized change tracking, optimized cache lookups)

When enabled, it provides all these features transparently and hence boosts the performance of your application.

Unfortunatly it also changes the identity of objects. You cannot do a instanceof anymore with weave'd objects.
