Linux and PostgreSQL in the Multiverse of Connections | POSETTE: An Event for Postgres 2026
Mapping Postgres shared buffers with huge pages drastically cuts page-table memory overhead when scaling to many connections.
“we shall stop guessing and start tuning our systems”
A credativ engineer gives a POSETTE 2026 deep dive on how Postgres's multi-process architecture imposes Linux memory and CPU overhead per connection, showing how huge pages and NUMA-aware tuning reduce page-table bloat. It is a technical database-scaling talk with no meaningful AI industry signal.
