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
