Summary
The article explores the implementation of Unix pipes in Linux by optimizing a test program for writing and reading data through a pipe. It starts with a throughput of 3.5GiB/s and aims to improve it twentyfold, guided by profiling with Linux's perf tooling. The goal is to match the speed of a highly optimized FizzBuzz program that achieves ~35GiB/s output on the author's laptop.

· 3 pulledWe will begin with a simple program with a throughput of around 3.5GiB/s, and improve its performance twentyfold.
The post was inspired by reading a highly optimized FizzBuzz program, which pushes output to a pipe at a rate of ~35GiB/s on my laptop.
Our first goal will be to match that speed, explaining every
