Abstract

Illustrative embodiments provide a computer implemented method, a data processing system and a computer program product for lock contention reduction. In one illustrative embodiment, the computer implemented method provides a lock to an active thread, increments a lock counter, receives a request to de-schedule the active thread, and determines whether the lock is held by the active thread. The computer implemented method, responsive to a determination that the lock is held by the active thread, adds a first pre-determined amount to a time slice of the active thread.
