+# CPU Governance
+
+Your server has a concept of CPU governance, which controls how the CPU manages its frequency and power consumption. There are several governor modes available, each with different characteristics.
+
+## Available CPU Governors
+
+| Governor       | Description                                        |
+| -------------- | -------------------------------------------------- |
+| `performance`  | CPU runs at maximum frequency at all times         |
+| `powersave`    | CPU runs at minimum frequency to save power        |
+| `ondemand`     | CPU frequency scales based on current load         |
+| `conservative` | Similar to ondemand but more gradual scaling       |
+| `userspace`    | Allows manual control of CPU frequency             |
+| `schedutil`    | Uses scheduler information for frequency decisions |
+
+## Recommended Configuration
+
+For game servers, it is **strongly recommended** to set the CPU governor to `performance` to ensure consistent, low-latency performance.
+
+## Ubuntu/Debian Configuration
+
+If you're using Ubuntu or Debian, you can install `cpufrequtils` and configure the governor:
+
+1. Install cpufrequtils:
+
+   ```bash
+   apt update
+   apt install cpufrequtils
+   ```
+
+2. Edit the configuration file:
+
+   ```bash
+   nano /etc/default/cpufrequtils
+   ```
+
+3. Set the governor to performance:
+
+   ```bash
+   GOVERNOR="performance"
+   ```
+
+4. Restart the service:
+   ```bash
+   systemctl restart cpufrequtils
+   ```
+
+## Verification
+
+To verify your current CPU governor settings:
+
+```bash
+cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
+```
