- You really want to make sure the header and bulk data end up in one TCP frame. If you utilize sendfile(), it isn't possible to guarantee that because you'll have to do two seperate operations: one write() to do the header data, then the sendfile() call to move the bulk data (right now writev() is used so header data and bulk data get coalesced into one TCP frame).
I think it should be possible to achieve the same result with sendfile() and TCP_CORK. This may be for Linux only however.
