An analysis of performance evolution of Linux’s core operations Ren et al., Perhaps the most interesting lesson/reminder is this: it takes a lot of effort to tune a Linux kernel. Google’s data center kernel is carefully performance tuned for their workloads. SOSP’19. Headline results. Security related root causes.

This was a weird problem to think about: Time itself had now become a resource and target of performance analysis. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. I'm including this step as a reminder for anyone following this kind of analysis.
