Monitoring Compton Resource Usage in CentOS
To effectively manage Compton’s impact on system performance, you need to monitor its CPU and memory consumption. Common tools for this purpose include:

  • top/htop: Run ps aux | grep compton to get real-time details (CPU%, memory usage) of the Compton process. For a more user-friendly interface, use htop (install via yum/dnf install htop if needed) to sort processes by memory (F6%MEM) and identify Compton’s resource usage.
  • systemd: If Compton runs as a systemd service (common in modern CentOS versions), use systemctl status compton to view its current resource utilization, including CPU and memory usage.
  • Sorting Processes: Use ps aux --sort -%mem | head to list processes by memory usage—this helps quickly determine if Compton is a top consumer.

Optimizing Compton Configuration for Better Performance
Compton’s resource usage is heavily influenced by its configuration. To reduce overhead:

  • Disable Unnecessary Effects: Turn off shadows (shadow = false) and window transparency (opacity = false) in the configuration file (typically ~/.config/compton.conf). These effects are visually appealing but demand significant GPU/CPU resources.
  • Enable GPU Acceleration: Set backend = glx (or wayland if supported) in the config file. This leverages your GPU for rendering, drastically improving performance compared to the default xrender backend. Ensure your graphics drivers (e.g., NVIDIA/AMD) are up-to-date.
  • Adjust Refresh Rate: Set vsync = true to synchronize Compton’s frame rate with your monitor’s refresh rate, reducing screen tearing and CPU load. Alternatively, set it to false if you experience lag.
  • Limit Resource Usage: Use cpulimit to cap Compton’s CPU usage (e.g., cpulimit -l 50 -p $(pgrep compton) limits it to 50%). For long-term control, create a systemd service file with CPUQuota=50% to enforce limits at the service level.

Additional Tips for Stable Performance

  • Update Compton: Regularly update to the latest version (via yum/dnf upgrade compton) to benefit from performance bug fixes and optimizations.
  • Use Lightweight Alternatives: If Compton still causes lag on low-end hardware, consider switching to lighter window managers like Openbox or i3, which have built-in compositing with lower overhead.
  • Monitor System-Wide Performance: Use tools like glances or vmstat to track overall CPU, memory, and disk usage. This helps identify if Compton is the primary bottleneck or if other processes are contributing to slowdowns.
