Example methods and apparatus to manage object locks are disclosed. A disclosed example method includes intercepting a processor request to apply the lock on the object, identifying a performance history of the object based on a number of instances of contention, reducing computing resources of the processor by, when the number of instances is below a threshold value, generating a lock bypass for the object to cause speculative execution of target code within the object, and preventing speculative execution by applying the lock on the object when the number of instances is above the threshold value.
