All diagnostic and tuning commands verified on all three versions. Persistence methods (NM dispatcher, sysctl.d, udev) confirmed working across reboots on each version. Assisted-by: Claude claude-sonnet-4-6 Co-Authored-By: Howard Van Der Wal <hvanderwal@ciq.com>
Add 8 references to authoritative kernel documentation, irqbalance, ethtool, NetworkManager dispatcher, and tuned project sources. Uses superscript notation matching Rocky Linux formatting guidelines. Assisted-by: Claude claude-sonnet-4-6 Co-Authored-By: Howard Van Der Wal <hvanderwal@ciq.com>

Written with help from Claude. Went through and reviewed the article against https://docs.rockylinux.org/guides/contribute/expert_contributing/?h=expert+contribution , https://docs.rockylinux.org/guides/contribute/ai-contribution-policy/ and https://docs.rockylinux.org/guides/contribute/rockydocs_formatting/ . All commands in the article have been tested on Rocky Linux 8.10, 9.7 and 10.1. The network performance tips are from my experience and hopefully they can help the entire community if they are implementing CPU pinning and observing network drops on the kernel side.
