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)).
What you describe below is less effective, since you need to ask the
kernel to read the dat

You can effectively stream a file byte by byte - you just need to print
a chunk at a time and mod_perl and apache will handle it
appropriately... I do this all the time to handle large data downloads
(the systems I manage are backed by peta bytes of data)...
The art is often not in the output
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?

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