For a long time (3.x, 4.0, 4.1 days) the buffer cache and VM system had serious breakage when it came to oddly sized buffers and we spent a long time fixing that. So far nobody has been able to determine whether the fragment ratio breakage (when it can be reproduced at all) is due to bugs in UFS or if there are still bugs in the buffer cache. -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
