You'd context switch to/from kernel way more often with small ranges. sendfile on Solaris, Linux, BSD and TransmitFile on Windows allow much larger ranges in one call. What's the replacement for sendfile(2)? Solaris has sendfilev which is still pretty much the same thing and sendfile(2) on Linux uses splice(2), vmsplice(2), tee(2) internally but I don't know of a replacement.
