Well, I could possibly live with 256MB, but the vnode/fsnode consumption seems to be getting a bit silly in the memory overhead department, even for machines with 4GB of RAM. It seems like there needs to be fewer of them and/or they need to go on a diet. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
