I have put all distribution files on a machine and installed three PCs via FTP from that machine. The installation process should access the same files, the buffer cache can be used to improve effieciency on the filesystem side. I am wondering whether some sort of optimization is done on the TCP/IP side in this situation. Do we have to copy data from buffer-cache to mbuf each time we need to send the data over network? As far as I know, the buffer cache has identity associated with it (vnode, block #), but the mbuf does not. Any help is appreciated. -Zhihui To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
