# zram-optimizer — High-Performance Swap Engine Skill ## When to Use Activate this skill when: - Setting up or replacing swap on a Linux system - Optimizing zram for maximum responsiveness - Benchmarking compression algorithms (`lz4`, `lzo-rle`, `zstd`) - Tuning kernel VM parameters (`swappiness`, `page-cluster`) - Replacing slow disk-based swap with in-memory compressed swap - The user wants a "raw-RAM-like" or "near-RAM-speed" swap experience ## Overview This skill provides a complete, **deterministic**, data-driven workflow for deploying a high-performance zram swap engine on any Linux system. It follows the **OpenEvolve pattern**: build an evaluator, test all combinations, and deploy the empirically proven winner. ### Key Principle: No Guesswork Instead of using generic defaults, this skill: 1. **Detects** the system's hardware (RAM, CPU cores) 2. **Benchmarks** every relevant zram parameter combination 3. **Ranks** configurations by a deterministic fitness score 4. **Deploys** the objectively fastest profile ## Prerequisites ### Install `zram-config` from GitHub ```bash # 1. Clone the repository sudo git clone https://github.com/ecdye/zram-config /opt/zram-config # 2. Install cd /opt/zram-config sudo ./install.bash # 3. Verify installation systemctl status zram-config cat /etc/ztab ``` > [!IMPORTANT] > The `/etc/ztab` file is the single source of truth for zram configuration. All changes are made here and applied by `systemctl restart zram-config`. ### Syste
