From: Steve Carlson To: Message-ID: Mime-version: 1.0 Content-type: text/plain; charset="US-ASCII" Content-transfer-encoding: 7bit Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hello all... I'm trying to figure out at what point I can expect performance issues with an FFS filesystem if I have directories with a massive number of small files or symlinks. As far as I understand it, there are a number of inodes located within a cylinder group, and the inodes for files are ideally placed in the same cylinder group as their parent directory. But if I were to have a massive number of small files or symlinks in a directory, wouldn't I run out of local inodes and thus start to see a performance issue when working in that directory? How can I determine the maximum number of files I should safely place in a directory without my performance suffering? Thanks for any help you can offer, Steve -- Steve Carlson NBC Internet To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
