Back during the Linux 5.18 merge window in March I wrote about a big NUMA benchmark performance regression I noticed and bisected.

Earlier this week AWS announced general availability on their new Arm Neoverse-V1 based processors, Graviton3. Right after that I posted some initial Graviton3 benchmarks against prior-generation Graviton2 for showing the very sizable generational improvement with Amazon's new in-house Arm server processors. Since then I have been carrying out a more robust set of around 100 benchmarks across the original Graviton instance, Graviton2, Graviton3, and then up again Intel Xeon and AMD EPYC competing instances. Here is that much larger collection of Graviton3 performance benchmarks carried out on Ubuntu 22.04 LTS.
