Squeezing Every Megabyte: Optimizing an 8GB NVIDIA Jetson Orin Nano for Headless ROS 2 and Edge-AI

Squeezing Every Megabyte: Optimizing an 8GB NVIDIA Jetson Orin Nano for Headless ROS 2 and Edge-AI

Short summary

A detailed engineering log for optimizing an 8GB NVIDIA Jetson Orin Nano for headless ROS 2 and Edge-AI workloads. By switching to multi-user target, disabling unnecessary daemons, and tuning swappiness, idle RAM drops from ~913 MiB to ~600 MiB. Covers headless SSH setup, service triage, and preserving critical services like nvargus-daemon for CSI cameras.

  • •Disable GNOME desktop to save 200+ MiB RAM on Jetson Orin Nano 8GB
  • •Disable non-essential daemons (samba, bluetooth, lttng, iperf3) for robotics use
  • •Lower swappiness to 10 to protect flash storage and reduce latency

Generated with AI, which can make mistakes.
