Hello,
I encountered the large file download before. I recalled that when
sendfile directive is turned on httpd.conf, it uses sendfile(2) system
call. It is more efficient than combination of read(2) and write(2) since
sendfile is operating within the kernel.
However, my question is if the large
sendfile is much more efficient than that. At the most basic level,
sendfile allows a file to be streamed directly from the block device (or
OS cache) to the network, all in kernel-space (see sendfile(2)).

Yeah, sendfile() is how I've done this in the past, although I was using
mod_perl 1.x for it.

sendfile sounds like its exactly what I'm looking for. I see it in the API
documentation for Apache2::RequestIO but how do I get a reference to it
from the reference to Apache2::RequestRec which is passed to my handler?

You can effectively stream a file byte by byte - you just need to print

The art is often not in the output
