## Overview
|
||||
|
||||
RAM Optimizer is a Claude Code skill that automatically configures Linux systems with advanced memory compression techniques. It uses the kernel's ZRAM module to create compressed swap space directly in RAM, effectively doubling or tripling your available memory without any hardware upgrades.

|
||||
## Installation
|
||||
|
||||
### Prerequisites

- Supported distributions: Ubuntu, Debian, Fedora, Arch Linux
|
||||
|
||||
### Quick Install
|
||||
|
||||
```bash
|
||||
# Using Claude Code CLI, simply ask:
|
||||
"Run ram optimizer on this server"
|
||||
|
||||
# Or manually:
|
||||
sudo bash scripts/setup-zram.sh
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Local Machine
|
||||
|
||||
```
|
||||
"Optimize RAM on this machine"
|
||||
"Boost memory on my laptop with 50% zram"
|
||||
```
|
||||
|
||||
### Remote Server
|
||||
|
||||
```
|
||||
"Run ram optimizer on SSH IP: 192.168.1.100, User: admin, Pass: secret"
|
||||
"Setup ZRAM on my VPS - SSH details: user@myserver.com with password xyz"
|
||||
```
|
||||
|
||||
### Custom Configuration
|
||||
|
||||
```
|
||||
"Optimize RAM with these settings:
|
||||
- 100% zram allocation
|
||||
- zstd algorithm for maximum compression
|
||||
- keep existing disk swap"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration Options
|
||||
|
||||
| Parameter | Default | Description |
|
||||
|-----------|---------|-------------|
|
||||
| `PERCENT` | 75% | Percentage of RAM allocated to ZRAM |
|
||||
| `ALGO` | lz4 | Compression algorithm (lz4/zstd/lzo) |
|
||||
| `PRIORITY` | 100 | Swap priority (higher = prefer ZRAM) |
|
||||
|
||||
---
|
||||
|
||||
## Monitoring
|
||||
|
||||
After installation, monitor your ZRAM usage:
|
||||
|
||||
```bash
|
||||
# View ZRAM status
|
||||
zramctl
|
||||
|
||||
# View swap usage
|
||||
swapon --show
|
||||
|
||||
# View detailed memory info
|
||||
free -h
|
||||
|
||||
# Monitor in real-time
|
||||
watch -n 1 'zramctl; echo; free -h'
|
||||
```
|
||||
|
||||
### Expected Output
|
||||
|
||||
```
|
||||
NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT
|
||||
/dev/zram0 lz4 5.7G 1.7G 713.9M 729.2M [SWAP]
|
||||
|
||||
total used free shared buff/cache available
|
||||
Mem: 7.6Gi 6.6Gi 130Mi 668Mi 1.8Gi 1.0Gi
|
||||
Swap: 5.7Gi 1.7Gi 4.0Gi
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
| Issue | Solution |
|
||||
|-------|----------|
|
||||
| ZRAM won't start | Check for conflicting swap configurations |
|
||||
| High CPU usage | Switch to `lz4` algorithm (fastest) |
|
||||
| Low compression ratio | Try `zstd` algorithm for better compression |
|
||||
| Still out of memory | Increase `PERCENT` to 100 or add physical RAM |

# RAM Optimizer Skill
|
||||
|
||||
This skill optimizes Linux system memory by setting up ZRAM compressed swap, enabling KSM (Kernel Samepage Merging), and applying sysctl optimizations for low-memory systems.
|
||||
|
||||
## What It Does
|
||||
|
||||
1. **ZRAM Setup**: Creates compressed RAM-based swap (typically 2:1 to 3:1 compression ratio)
|
||||
2. **KSM Enablement**: Deduplicates identical memory pages
|
||||
3. **Sysctl Tuning**: Optimizes kernel memory management parameters
|
||||
4. **Optional**: Removes traditional disk swap to free space and improve performance
|
||||
|
||||
## When To Use This Skill
|
||||
|
||||
Activate this skill when the user:
|
||||
- Asks to optimize RAM/memory on a Linux system
|
||||
- Mentions running low on memory
|
||||
- Wants to set up ZRAM or memory compression
|
||||
- Needs to boost a server with limited RAM
|
||||
- Mentions "effective memory" or "RAM compression"
|
||||
|
||||
## Supported Systems
|
||||
|
||||
- Ubuntu/Debian (apt-based)
|
||||
- Fedora/RHEL/CentOS (dnf/yum-based)
|
||||
- Arch Linux (pacman-based)
|
||||
|
||||
## Usage Instructions
|
||||
|
||||
### For Local Machine
|
||||
Simply run the skill and it will detect and optimize the local system.
|
||||
|
||||
### For Remote SSH Server
|
||||
Provide SSH credentials in one of these formats:
|
||||
- `SSH IP: x.x.x.x, SSH User: username, SSH Pass: password`
|
||||
- Or mention the server details in your request
|
||||
|
||||
## Configuration Options
|
||||
|
||||
The user may request these customizations:
|
||||
- **ZRAM percentage**: Default is 75% of RAM. User can request 50%, 100%, etc.
|
||||
- **Compression algorithm**: Default is `lz4` (fastest). Alternatives: `zstd` (better compression), `lzo`
|
||||
- **Keep or remove disk swap**: Default removes disk swap. User can request to keep it.
|
||||
- **Install monitoring**: User can request Conky (desktop widget) or btop (terminal monitor)
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
When this skill is invoked, follow these steps:
|
||||
|
||||
### Step 1: Detect Target System
|
||||
```bash
|
||||
# For local:
|
||||
cat /etc/os-release
|
||||
free -h
|
||||
|
||||
# For remote:
|
||||
ssh user@host 'cat /etc/os-release; free -h'
|
||||
```
|
||||
|
||||
### Step 2: Install ZRAM Tools
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
apt install -y zram-tools
|
||||
|
||||
# Fedora
|
||||
dnf install -y zram
|
||||
|
||||
# Arch
|
||||
pacman -S zram-generator
|
||||
```
|
||||
|
||||
### Step 3: Configure ZRAM
|
||||
```bash
|
||||
# /etc/default/zramswap (Debian/Ubuntu)
|
||||
ALGO=lz4
|
||||
PERCENT=75
|
||||
PRIORITY=100
|
||||
```
|
||||
|
||||
### Step 4: Enable KSM
|
||||
```bash
|
||||
echo 1 > /sys/kernel/mm/ksm/run
|
||||
echo 1000 > /sys/kernel/mm/ksm/sleep_millisecs
|
||||
```
|
||||
|
||||
### Step 5: Apply Sysctl Optimizations
|
||||
```bash
|
||||
# /etc/sysctl.d/99-lowram.conf
|
||||
vm.swappiness=100
|
||||
vm.vfs_cache_pressure=200
|
||||
vm.compaction_proactiveness=30
|
||||
vm.overcommit_memory=1
|
||||
vm.overcommit_ratio=50
|
||||
vm.ksm.run=1
|
||||
```
|
||||
|
||||
### Step 6: Start ZRAM Service
|
||||
```bash
|
||||
systemctl enable --now zramswap.service
|
||||
```
|
||||
|
||||
### Step 7: (Optional) Remove Disk Swap
|
||||
```bash
|
||||
swapoff /swapfile
|
||||
rm /swapfile
|
||||
sed -i '/\/swapfile/d' /etc/fstab
|
||||
```
|
||||
|
||||
## Expected Results
|
||||
|
||||
| Metric | Typical Value |
|
||||
|--------|---------------|
|
||||
| Compression ratio | 2:1 to 3:1 |
|
||||
| RAM reduction | ~40% average |
|
||||
| CPU overhead | 1-3% |
|
||||
| Effective memory | Physical × 2 |
|
||||
|
||||
## Verification Commands
|
||||
|
||||
```bash
|
||||
# Show ZRAM status
|
||||
zramctl
|
||||
|
||||
# Show swap status
|
||||
swapon --show
|
||||
|
||||
# Show memory
|
||||
free -h
|
||||
|
||||
# Show compression efficiency
|
||||
cat /sys/block/zram0/mm_stat
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
- **ZRAM won't start**: Check if another swap is using high priority
|
||||
- **High CPU usage**: Switch to lz4 algorithm (fastest)
|
||||
- **Low compression ratio**: Try zstd algorithm for better compression
|
||||
- **Out of memory still**: Increase PERCENT to 100 or add physical RAM
