Actually, I'd say it's more along the opposite of this :-) There are patches for 4.0, IIRC, that do zero copy sockets and NFS. They are located at: http://people.freebsd.org/~ken/zero_copy/ I've been looking at them recently to see what it'd take to move it to -current and 4.4.. but definetly have not done anything worth looking at. Hope this helps, Andrew On Tue, 13 Nov 2001, CJTT wrote: : :Do you have to be running Current in order to use the :zero copy sockets? If so, when will this make it to :Stable?
