Proxmox Optimization Guide — Free Preview
This free preview includes the ZFS storage optimization section and the LXC vs VM decision matrix. The complete guide covers 8 phases: Post-Install Setup, Storage Optimization, VM/LXC Optimization, Backup Strategy, Performance Monitoring, Security Hardening, GPU Passthrough, and Advanced Topics.
ZFS Compression Comparison (from the guide):
| Algorithm | Speed | Ratio | Recommendation |
|---|---|---|---|
| lz4 | Very fast | ~1.5-2x | Default choice |
| zstd-3 | Medium | ~2.5-3x | Recommended for storage |
| zstd-19 | Very slow | ~3-3.5x | Cold storage only |
What's in the full guide:
- Phase 1: Post-Install Essentials (repos, network, banner removal)
- Phase 2: Storage Optimization (ZFS pools, recordsize, ARC tuning, scrubs)
- Phase 3: VM & LXC Optimization (CPU, memory, network, disk settings)
- Phase 4: Backup Strategy (PBS, schedules, verification)
- Phase 5: Performance Monitoring (metrics, alert thresholds)
- Phase 6: Security Hardening (SSH, fail2ban, 2FA, firewall)
- Phase 7: GPU Passthrough (IOMMU, VFIO, VM assignment)
- Phase 8: Advanced Topics (HA, replication, cloud-init)
- Bonus: Quick command reference + optimization checklist
