We will proceed as follows:

A first slow version of our pipe test bench;

How pipes are implemented internally, and why writing and reading from them is slow;

How the vmsplice and splice syscalls let us get around some (but not all!) of the slowness;

A description of Linux paging, leading up to a faster version using huge pages;

The final optimization, replacing polling with busy looping;

Some closing thoughts.
