Lock contention determination

Hi all
If I have a lockstat report showing that some lock has more waiting time
than holding time, can I assert that this lock is (one of) the performance
bottlenecks? Here performance bottleneck means we could optimize lock
usage, e.g. reduce the size of critical section etc.
If not, why?
Thanks beforehand

Best regards
Chen, Yiqun
