Have you read the XFS tuning recommendations? The XFS developers bitch because people don't tune their volumes, then they don't understand bad performance...
notes from Gentoo install: <snip> Note: You may want to add a couple of additional flags to the mkfs.xfs command: -d agcount=3 -l size=32m. The -d agcount=3 command will lower the number of allocation groups. XFS will insist on using at least 1 allocation group per 4 GB of your partition, so, for example, if you hava a 20 GB partition you will need a minimum agcount of 5. The try this w/ XFS <snip> mkfs.xfs -d agcount=(numgigs / 4) -l size=32m ===THEN== when you mount, try logbuf=8 and noatime in the mount options. Windows is a killer for atimes. js On Fri, 2003-01-10 at 07:05, Gerald Drouillard wrote: > Unless you are a programmer, I am afraid the only thing you can do is to > modify how the files are stored in that directory.
