Modern servers operate with terabytes of RAM, and by default, processors work with virtual memory address translation for each 4KB page. OS maintains a huge list of allocated and free pages to make slow but reliable address translation from virtual to physical. Huge pages make PostgreSQL faster; can we implement it in Kubernetes?
