AWS Engineer Reports Postgres Performance Halved by Linux 7.0 — When running Postgres 17 on an ARM-based instance running the Linux 7.0 kernel (currently in RC), an engineer noticed performance fell by 49%, leading to a kernel patch to restore Linux’s default preemption mode. The kernel developer behind the initial change, however, says Postgres needs to modernize its locking instead – a big ask given Linux 7.0 is due to land later this month.
