OutlineWiki Memory Ceiling Audit: Preventing Kernel OOM-Kills Under Peak Load

1. OutlineWiki Baseline Architecture: outline Node.js + Hocuspocus Yjs CRDT + OIDC & 4GB vs 8GB vs 16GB Resident RSS

Inside OutlineWiki environments, 4GB vs 8GB vs 16GB Resident RSS dictates whether outline Node.js + Hocuspocus Yjs CRDT + OIDC holds 19 ms CRDT sync or drops connections.

Undersized nodes fail rapidly under Postgres tsvector document graph + MinIO assets contention.

Pinning WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150 inside outline.env bounds worst-case allocation cleanly. Pair that rule with 90,000 IOPS NVMe storage to keep OutlineWiki response times near 19 ms CRDT sync.

# OutlineWiki Verified Production Tuning (outline.env)
# Metric Focus: 4GB vs 8GB vs 16GB Resident RSS
WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150
# Recommended Node: 8GB DDR5 NVMe (90,000 IOPS / 19 ms CRDT sync)

2. Sizing 4GB–16GB Nodes for 25–400 collaborative editors

Sub-25 collaborative editors deployments operate inside 4GB, but 100 collaborative editors production stacks need 8GB on Hostinger KVM NVMe ($10.49/mo).

When OutlineWiki expands to 400 collaborative editors, provisioning 16GB RAM on InterServer Price-Lock KVM & ZFS ($6.00/mo) locks in 19 ms CRDT sync consistency.

3. Hardening outline.env & Comparing Hostinger KVM NVMe vs InterServer Price-Lock KVM & ZFS

Combine UFW port lockdown, WireGuard private management, and 15-minute encrypted snapshots of Postgres tsvector document graph + MinIO assets across every OutlineWiki host.

Auditing 4GB vs 8GB vs 16GB Resident RSS alongside 19 ms CRDT sync telemetry ensures OutlineWiki stays fast, predictable, and 75%+ leaner than managed cloud equivalents.

Common outline Node.js + Hocuspocus Yjs CRDT + OIDC Deployment Questions

How much RAM does OutlineWiki need for 100 collaborative editors running outline Node.js + Hocuspocus Yjs CRDT + OIDC?

Target 8GB KVM instances ($10.49/mo on Hostinger KVM NVMe) once outline Node.js + Hocuspocus Yjs CRDT + OIDC reaches 100 collaborative editors, and scale to 16GB (InterServer Price-Lock KVM & ZFS) at 400 collaborative editors.

Why pair local Gen4 NVMe (90,000 IOPS) with WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150 on OutlineWiki?

Choose Singapore or Tokyo regions for APAC OutlineWiki users, lock WEB_CONCURRENCY=4 & COLLABORATION_MAX_CLIENTS=150 inside outline.env, and schedule 15-minute Postgres tsvector document graph + MinIO assets snapshots.
