- * Although FreeBSD sendfile() allows to pass a header and a trailer,
- * it cannot send a header with a part of the file in one packet until
- * FreeBSD 5.3.  Besides, over the fast ethernet connection sendfile()
- * may send the partially filled packets, i.e. the 8 file pages may be sent
- * as the 11 full 1460-bytes packets, then one incomplete 324-bytes packet,
- * and then again the 11 full 1460-bytes packets.
- *
- * Therefore we use the TCP_NOPUSH option (similar to Linux's TCP_CORK)
- * to postpone the sending - it not only sends a header and the first part of
- * the file in one packet, but also sends the file pages in the full packets.
- *
- * But until FreeBSD 4.5 turning TCP_NOPUSH off does not flush a pending
- * data that less than MSS, so that data may be sent with 5 second delay.
- * So we do not use TCP_NOPUSH on FreeBSD prior to 4.5, although it can be used
- * for non-keepalive HTTP connections.
