X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 08 Jul 2007 19:02:23 -0000 I have a filesystem that a lot of deletions and intra-filesystem copying (cp) are done. System is FreeBSD 6.2-RELEASE, i386 32-bit, SATA drives attached to twa0: <3ware 9000 series Storage Controller>. It is a 8 TB filesystem that I created with: newfs -i 32768 -U /dev/da2 I have done no further optimization to this filesystem, the kernels, or the disks, etc. I would like very much for rm and cp processes (copying files from one place to another on the same filesystem) on this filesystem to complete more quickly. Is there any kind of tuning I can do to achieve this ? If so, what expenses do I incur in other operations ? The CPU and ram on this system are both essentially at zero. The 4 GB of ram is barely used, and the 4 GB of swap has never been touched. All comments and suggestions appreciated. ____________________________________________________________________________________ Now that's room service!
