Jason, your question is really generic and I think you're talking about DB2 locks.
To obtain a lock DB2 must use CPU so the more locks the more CPU you need. This usually is related to a workload growth or application change. If the number of locks is quite the same and the number of lock contentions should increase and you need to investigate if it could increase CPU usage then it's possible (or better sure) because the lock contention management burns CPU too. The larger is the number of locks and the longer is the queue on a given resource then the more CPU DB2 needs to manage it. If the happening is so hard to make you ask a question you can give us some other lights. Maybe it's a good question for DB2 list. If you're in a Data Sharing environment it can be worst. Best regards.
