Anyone? Thanks! One of the "tricks" to handle this is to use a journaling filesystem. This allows the filesystem to initially drop the data in the journal and ack the NFS operation, giving it the chance to later write out the stuff to disk with some more freedom in optimising seeks. I'm not sure if there is a journaling filesystem available for BSD which does this, however. Another alternative would be to use LFS, but I don't think it's up-to-date for FreeBSD ... regards, Rik -- Hollywood goes for world dumbination, Trailer at 11. http://www.surriel.com/ http://www.conectiva.com/ http://distro.conectiva.com.br/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
