Subject: sendfile support in linux
Date: Mon, 27 Jan 2003 17:45:20 -0800 [thread overview]
Message-ID: <057889C7F1E5D61193620002A537E8690B4387@NCBDC> (raw)
I'm trying to find out more about sendfile(2). So far, from what I've
gathered, it sounds like the requirements for it are (please correct me if
I'm wrong):
1. A kernel with sendfile support (i.e. 2.4.X)
2. A network card capable of doing the TCP checksum in the hardware
3. The application must support sendfile
Do you know what applications support zerocopy (sendfile)? I noticed that a
zerocopy NFS patch was added to the 2.5.x tree. Does the 2.4.X NFS daemon
support zerocopy? Does samba support zerocopy and if so what version?
Only me,
Stanley Yee

sendfile(2) does zero-copy writes from files to sockets, works on any
version of 2.4 AFAIK.
