How fast are Linux pipes anyway?

Pipes are ubiquitous in Unix --- but how fast can they go on Linux? In this post we'll iteratively improve a simple pipe-writing benchmark from 3.5GiB/s to 65GiB/s, guided by Linux `perf`.

    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.

    "What do you mean, ‘What did I build that for?’ "

    This is exactly the kind of thing I like.
