In my opinion, the high-contention lock case is kind of a moot point because once there are many contenders for a lock, those contenders are stalled waiting for the lock, so if performance of the cache system is low (causing cores to wait), it isn't all that terrible - the high-contention lock should be eliminated by the programmer anyway.
