Linux vs Windows Optimization

Choosing between Linux (Ubuntu/Debian) and Windows Server is more than just personal preference. Each OS requires specific 'hardening' and optimization to run 7DTD smoothly.

Linux (Ubuntu 22.04+) Optimization

Linux is generally 10-15% more efficient in its RAM usage for 7DTD. However, you must tune the kernel:

  • File Limits: Increase ulimit -n to at least 65535 to prevent the game from crashing during high player counts.
  • No-GUI: Always run your Linux server in 'Headless' mode to save 1GB+ of RAM for the game process.

Windows Server Optimization

If you prefer Windows, ensure you are running Windows Server 2022 Core (if possible) or follow these steps:

  • High Performance Power Plan: Essential to prevent CPU down-throttling during idle moments.
  • Process Priority: Set the 7DaysToDieServer.exe priority to 'Above Normal' in the task manager.
