Intel Sapphire Rapids Performance With Google Cloud Compute Engine C3
Back in October Google announced their Compute Engine C3 instances in private preview that featured 4th Gen Xeon Scalable "Sapphire Rapids" processors as well as making use of Google's custom Intel Infrastructure Processing Unit (IPU). Since then, back in January, was the big Sapphire Rapids launch with the likes of the Xeon Platinum 8490H being released. Last month meanwhile Google promoted the C3 VMs to public preview state. The Sapphire Rapids C3 VMs remain in "public preview" from Google Cloud during which time there are no charges involved for the CPU costs. For those wondering about the core-for-core performance of Sapphire Rapids in Google Cloud, here are my initial benchmarks of the C3 series.

With the Linux 6.2 release kernel developers addressed "a tasty target for attackers" after it was realized that the per-CPU entry data was not being randomized, even in the presence of Kernel Address Space Layout Randomization (KASLR). The per-CPU entry area randomization has been present since Linux 6.3 but then was realized it's being activated even if KASLR was disabled, so now that is changing to avoid possible confusion...
