```
<div class="warning">The warning text</div>
```

Don't hesitate to use it. :)

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`.
