As far as I've understood, sendfile() won't do much good with large files. Is this right?
There is always a benefit to using sendfile(), when you use sendfile() the cpu doesn't touch one byte of the data if the network card support TX checksumming. The disk DMAs to ram, then the net card DMAs from ram. Simple as that.
