A method, apparatus and system for, in a computing apparatus, comparing a measure of data contention for a group of operations protected by a lock to a predetermined threshold for data contention, and comparing a measure of lock contention for the group of operations to a predetermined threshold for lock contention, eliding the lock for concurrently executing two or more of the operations of the group using two or more threads when the measure of data contention is approximately less than or equal to the predetermined threshold for data contention and the measure of lock contention is approximately greater than or equal to a predetermined threshold for lock contention, and acquiring the lock for executing two or more of the of operations of the group in a serialized manner when the measure of data contention is approximately greater than or equal to the predetermined threshold for data contention and the measure of lock contention is approximately less than or equal to a predetermined threshold for lock contention. Other embodiments are described and claimed.
