Network Optimization Tutorial For NVIDIA Jetson AGX Orin 64 GB

Abstract This tutorial documents a systematic approach to network performance optimization on an NVIDIA Jetson AGX Orin Developer Kit 64 GB running Ubuntu 22.04.5 LTS (aarch64) with JetPack 6.2.2, CUDA 12.6, cuDNN 9.3.0, OpenCV 4.8.0, and TensorRT 10.3.0.30. The procedure covers kernel TCP buffer tuning, MTU adjustment on the eno1 wired interface, APT parallel download configuration, and aria2 multi-connection download tooling. All steps include pre-change backups and a dedicated revert procedure. The guide is structured as a production-oriented, step-by-step procedure rather than a reference summary. It includes a consolidated interactive Bash script that auto-detects the primary wired interface (eno1 or eth0), backs up affected configuration files before any changes, and applies each optimization only with explicit operator consent. Troubleshooting guidance is included for the RTNETLINK answers: Device or resource busy error encountered during MTU changes on Jetson hardware. System a
