As some additional end-of-year kernel benchmarking, here is a look at the Linux 4.14 versus 4.20 kernel benchmarks on the same system for seeing how the kernel performance changed over the course of 2018. Additionally, Linux 4.20 was also tested a second time when disabling the Spectre/Meltdown mitigations that added some performance overhead to the kernel this year...

Last month Amazon rolled out their "Graviton" ARM processors in the Elastic Compute Cloud. Those first-generation Graviton ARMv8 processors are based on the ARM Cortex-A72 cores and designed to offer better pricing than traditional x86_64 EC2 instances. However, our initial testing of the Amazon Graviton EC2 "A1" instances didn't reveal significant performance-per-dollar benefits for these new instances. In this second round of Graviton CPU benchmarking we are seeing what is the fastest of five of the leading ARM Linux distributions.

With the end of the year quickly approaching, it's time for our annual look at how the Linux performance has evolved over the past year from graphics drivers to distributions. This year was a particularly volatile year for Linux performance due to Spectre and Meltdown mitigations, some of which have at least partially recovered thanks to continued optimizations landing in subsequent kernel releases. But on the plus side, new releases of Python, PHP, GCC 8, and other new software releases have helped out the performance. For kicking off our year-end benchmark comparisons, first up is a look at how Intel's performance-optimized Clear Linux distribution evolved this year.

Initially during the Linux 4.20 kernel merge window with the STIBP addition for cross-hyperthread Spectre V2 mitigation it was turned on by default for all processes. But that turned out to have a sizable performance hit so the behavior was changed to only turn it on for processes under SECCOMP or when requested via the PRCTL interface. However, AMD is landing a patch that for select CPUs will have an always-on mode as evidently that's preferred for some AMD processors...

A new framework queued for introduction with the Linux 4.21 kernel is the ARM-developed Energy Model Management Framework...
