It will only be around 2% - thats way down in the noise.
However if you do have cr/lf line endings on your message on disk you
can then use something like sendfile() to fire the message out to your
pop/imap client, rather than having to read the file in and sending it a
line at a time (buffered obviously) rewriting the line ends as you do
so. This is likely to be noticeable CPU saving by just handing the file
over to a kernel event interface to send out.
Optimisation for large systems can be a really complex issue....
