🧩 1. Problem background: Clash verge memory usage is too high
When using Clash Verge as a VPN proxy tool in the Ubuntu desktop environment, the following problems often occur:
- Memory usage continues to grow (500MB+)
- The system freezes after a long operation
- Performance degradation when used with Firefox/Gnome
The essence is:
Electron architecture + real-time UI rendering + traffic statistics module
⚙️ 2. Optimization goals
This optimization goal:
- Keep the VPN function running properly
- Reduce the resident memory in the background
- Reduce UI resource usage
- Improve Ubuntu desktop stability
🛠️ 3. Optimization steps (core configuration stage)
1️⃣ Decrease the log level (important)
path:
设置 → Clash 设置 → 日志等级
Recommended settings:
- WARN (recommended)
- error (lighter)
function:
- Reduce log write
- Reduce UI refresh rate
2️⃣ Turn off traffic statistics UI
path:
设置 → 界面设置
Close:
- flow chart display
- Kernel occupancy display
function:
- Reduce Electron UI rendering load
3️⃣ Turn off unnecessary network functions
Suggestion:
- IPv6: close
- DNS overwrite: close
- LAN connection: closed (not required)
⚡ 4. Key steps: enable lightweight mode (last execution)
path:
Verge 高级设置 → 轻量模式设置 → 启用
⚠️ Note:
- UI disappears when enabled
- Must be executed after all configurations are complete
📊 5. Optimization effect comparison
| Status | memory usage |
|---|---|
| default mode | 400MB – 600MB |
| after optimization | 150MB – 220MB |
👉 Memory drop by about 60%
🧠 Six, core conclusions
The essence of the Clash Verge memory usage problem is:
UI rendering + real-time traffic statistics, not the VPN itself
Optimize the core idea:
- Reduce UI
- Reduce logs
- Enable lightweight mode at last
🔍 7. Applicable scenarios
Applicable to:
- Ubuntu 22.04 / 24.04 / 26.04
- Gnome / Wayland desktop
- Clash Verge long-term background running
- run firefox/chrome/vscode at the same time
