PREEMPT_NONE Is Dead; Your Postgres Probably Doesnโ€™t Care

A benchmark came out of AWS earlier this month showing PostgreSQL throughput on Linux 7.0 dropping to 0.51x what the same workload produced on Linux 6.x. The Phoronix headline wrote itself. Hacker News did what Hacker News does. By the end of the week, I had been asked by three separate clients whether they needed to hold their kernel upgrades.
They donโ€™t. Almost nobody does. The regression is real, but itโ€™s a narrow, loud artifact of a benchmark configuration that was already misconfigured for a 96-vCPU box with 100+ GB of shared memory. The headline undersells how much this is a โ€œdonโ€™t do thatโ€ story and oversells how much this is a Linux-broke-Postgres story
