## What it is
An educational guide explaining where common Linux network sysctl variables fit into the kernel's packet flow, covering ingress/egress queues, ring buffers, interrupt coalescing, QDiscs, and TCP buffers. It is a documentation/tutorial repository with diagrams and references rather than runnable software.

## Use cases
- understand linux network sysctl parameters
- learn how packets flow through the linux kernel
- tune tcp buffer sizes on linux
- understand napi and interrupt coalescing
- learn what rx-usecs and tx-usecs do
- troubleshoot linux network performance
- understand qdisc and txqueuelen

## When to choose
- you want to understand the Linux networking stack before tuning sysctl values
- you need a visual map of where network parameters act in the packet flow
- you are learning kernel networking concepts like NAPI, ring buffers, and QDiscs

## When to avoid
- you need an automated tuning tool that applies sysctl settings for you
- you want guaranteed 'cargo cult' sysctl values that work everywhere
- you need non-Linux network tuning guidance

## Facets
- artifact type: learning-resource
- maturity: stable
- function: networking, monitoring, developer-tools
- domain: networking, operating-systems, performance, tutorials
- platform: cli
- tags: sysctl, tcp-tuning, kernel-networking, napi, ring-buffer, interrupt-coalescing, qdisc, documentation, performance, linux
