## What it is
distcc is a distributed compilation front-end for C, C++, and Objective C that spreads compile jobs across machines on a network. It works with gcc and GNU make's parallel builds, requires no shared filesystem, and can be significantly faster than local compilation.

## Use cases
- speed up compiling large C/C++ projects across multiple machines
- distribute Linux kernel builds over a network
- reduce build times for projects like KDE or Samba using spare machines
- set up a distributed build farm without shared filesystems
- accelerate CI builds with parallel remote compilation
- use pump mode to offload preprocessing to remote servers

## When to choose
- you build large C/C++/Objective C codebases and have multiple networked machines available
- you want faster builds without requiring shared filesystems or identical machine setups
- you already use GNU make -j and gcc-compatible toolchains

## When to avoid
- your project is not C, C++, or Objective C
- you have only a single machine or a very fast local build
- you need distributed builds for languages with their own native distributed build tools
- network bandwidth between machines is very limited and pump mode is not viable
