PHP-FPM in cPanel speeds up PHP execution, but persistent workers consume RAM even when idle. Learn how to size pm.max_children per domain without triggering the OOM killer.
When memcached evicts items unexpectedly, the root cause is often an unexamined slab class size or -f factor. This article maps the memory layout, operational checks, and failure modes so you can size cache with confidence.
Proxmox VE hosts using ZFS for storage rely on the Adaptive Replacement Cache for read caching. By default ARC can consume a large share of host RAM, which creates tension with memory allocated to VMs and containers. The goal is to select an ARC limit that preserves guest memory availability while retaining ZFS read performance. There is no single documented
A Neo4j deployment serving a predominantly read‑only workload with limited concurrent users requires careful page cache sizing to balance memory efficiency against disk I/O. The dbms.pagecache_size setting governs the off‑heap cache that holds frequently accessed graph pages. Version‑specific default sizes and auto‑tuning behavior have changed between major
