Abstract
Controlling access to a resource by a plurality of resource requesters is disclosed. The resource lock operates in a contention efficient (heavyweight) operating mode, and in response to a request from a resource requester to acquire the resource lock, a count of a total number of acquisitions of the resource lock in the contention efficient operating mode is incremented. In response to access to the resource not being contended by more than one resource requester, a count of a number of uncontended acquisitions of the resource lock in the contention efficient operating mode is incremented, and a contention rate is calculated as the number of uncontended acquisitions in the contention efficient operating mode divided by the total number of acquisitions in the contention efficient operating mode. In response to the contention rate meeting a threshold contention rate, the resource lock is changed to a non-contention efficient (lightweight) operating mode.
