    Linus, no need to explain that to me, I'm precisely trying to see how
    to disable PTI for a specific process because I face up to 45% loss in
    certain circumstances, making it a no-go. But while a few of us have
    very specific workloads emphasizing this impact, others have very
    different ones and will not notice. For example my laptop did boot
    pretty fine and I didn't notice anything until I fire a network
    benchmark.
