Mazzoli: How fast are Linux pipes anyway?

Francesco Mazzoli delves
deeply into the kernel's implementation of pipes (and more) in an
attempt to maximize the throughput of data.

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 step as we go along. We’ll also add an additional
performance-improving measure, which is not needed in FizzBuzz
since the bottleneck is actually computing the output, not IO, at
least on my machine.
