## What it is
Tcpdive is a TCP performance profiling tool that monitors and analyzes TCP internals from a running Linux kernel using SystemTap, requiring no kernel modifications. It provides detailed metrics on transmission, loss and retransmission, congestion control, and HTTP processing at the TCP layer.

## Use cases
- profile TCP performance on a Linux server
- diagnose TCP retransmission and packet loss
- compare TCP performance in wired vs wireless networks
- analyze HTTP processing at the TCP layer
- quantify impact of TCP tuning changes
- characterize TCP traffic per application

## When to choose
- you need deep insight into TCP internals beyond tcpdump or netstat
- you want to profile TCP without modifying or patching the kernel
- you run a Linux production environment and need quantitative TCP metrics

## When to avoid
- you need a maintained tool - the last release was 2017
- you are on a non-Linux platform or a modern kernel unsupported by SystemTap scripts
- you need general packet capture rather than TCP performance profiling

## Facets
