Benchmarking huge_pages on a 128 GB PostgreSQL 18 system shows throughput gains are modest — but page table overhead at 4KB pages can consume up to 20% of total RAM. Use PSI to find where your system is actually stalling before making the call. Part 2 of 3.
Tuning shared_buffers isn't just about peak throughput — it's about how much CPU and disk I/O a system consumes per unit of work. The 25% default can require up to 5x more disk I/O than very low or very high allocation. Part 1 of 3.
A modern approach to IT observability inspired by hazard analysis. Learn how to improve system reliability, reduce monitoring complexity, and proactively manage service risks through Critical Control Points.
