Page faults are the very slow thing. When you boot, your cache is gonna start empty. Maybe it will run faster after it has been running a while. If you have a pretty stable linux machine, you might only re-boot once or twice in a pandemic. This situation may eventually be improved by some more secure run-time environment(?s) that somehow eliminate the need for hardware to mother hen so many memory accesses, but we might not be so happy to work under such a regime either.
