+**2. Kernel parameters** (target PCIe/NVMe link power saving + residual C‑states).

+Use the TrueNAS `midctl` command to add custom Kernel Boot Arguments, then reboot
+
+```bash
+midclt call system.advanced.config
+
+midclt call system.advanced.update '{"kernel_extra_options": "intel_idle.max_cstate=1 processor.max_cstate=1 pcie_aspm=off nvme_core.default_ps_max_latency_us=0"}'
 ```

 **3. CPU governor → `performance`** *(the single biggest win)*:
 ```bash
+grep MHz /proc/cpuinfo | sort -u
 echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
+grep MHz /proc/cpuinfo | sort -u
 ```
 Make it persistent on TrueNAS — *System → Advanced Settings → Init/Shutdown Scripts*, add a **Post Init** *Command*:
