It provides a secure tunnel for all my devices, especially ones that can't run a VPN. Best part? Efficiency! As you can see in the shot, it’s barely sipping power: only ~135MB of RAM and near 0% CPU. 🚀

I can toggle the VPN to manage remote IoT access while keeping a solid layer of protection. Small, silent, and rock solid.

I did the same on the same Pi but using Armbian: same result, just it was a bit tricky to setup.

​WireGuard runs in kernel space: it's invisible to the scheduler unless there's heavy traffic.
​Load measures the queue: on 4 cores with no tasks waiting, 0.00 is a perfect score.
​Irony: btop uses more CPU just to draw its UI than the VPN itself! I'd rather save those cycles for my data than for eye-candy 😆

It would give a better idea of the resources. Zero% seems unlikely

Real-world data is king. Though at these power levels, buying a $20 energy monitor to measure a ~$10/year electricity bill feels like overkill.

Not after theoreticals.

While htop doesn't show kWh, the physics of a Pi 4 are well-documented. At the idle state shown (near 0% CPU), it draws ~3W.
​Doing the math: 3W * 24h * 30 days = 2.16 kWh per month.
​Comparing that to your 55 kWh Windows setup? My gateway uses about 25 times less energy to do the same job 24/7. That’s the beauty of ARM vs x86 for simple networking tasks 😃

Question might be unclear so attaching a screenshot showing energy usage for the month for my windows machines. Tapo P110M used. Hint - you can’t get this from htop.

I know it’s not much but always looking for quantifiable data. You’ll need a kill-a-watt or energy monitoring plug.
