<p>Apparatus, methods, and computer program products are disclosed that improve the performance of multi-threaded computer applications that use objects (within an object collection) which require exclusive thread access. The invention monitors interrelationships between the objects in the object collection and provides mechanisms to lock the minimal set of these objects for the exclusive thread access. When these objects are locked, independent or unrelated objects are left unlocked and can, in turn, be locked by other threads. Because a minimal set of objects are locked other threads that access the object collection are less likely to be blocked by the lock. Thus, these other threads are more likely to be able to simultaneously access objects in the object collection. <IMAGE> <IMAGE> <IMAGE></p> |
