The sendfile facility allows a regular file to be sent out to a stream socket. The system call was first implemented in FreeBSD 3.1. This provides many performance benefits for various server appliances. Andre Opperman has implemented an improved sendfile facility for FreeBSD that has so far shown 45% less CPU usage without TCP segmentation offload and 83% less CPU usage with TCP segmentation offload. This is a great improvement over the previous implementation.

[O.k., so it's FreeBSD, not GNU/Linux - but few stories are cuter than "Penguin and the Beastie" - dcparris]
