The lock-based works *much* better than the lock free. The lock free allows all four threads to run, totally trashing the FSB. The locks allow only two threads to run at full speed, which not only get more work done than all four fighting for the FSB and playing cache ping-pong but also allow the system to accomplish other useful work as well.
