Oh really, "it has been stated". By who? Overall, I doubt that all of our security technologies add more than about 2% of a performance hit. Even a 'make build' on most architectures did not add that. I think you need to go back and read my slides again. Spreading lies about 5-10% performance hits is just not kind to our efforts.
