As to performance, I don't know much about JFS, but XFS is notoriously<br>
slow at file create / delete.<br></blockquote><div><br>What? I've been using XFS on a couple NFS servers for a couple years now. One exports Maildir repositories to a cluster of Qmail/Courier mail servers, and the other exports web directories to a cluster of Apache webservers, as well as acts as a backup server for my production VPS servers (each single file ranges from 4Gb to 80Gb in size). XFS beats the pants off ReiserFS and EXT3 when reading/writing a bunch of small files. I haven't noticed a difference one way or the other on creating large files, but deleting them is much faster in XFS.<br>

Seems like XFS used to take a couple minutes to do the delete!!!<br>
Obviously not a good choice of filesystem if you plan to do a lot of<br>
kernel development.</blockquote><div><br>WHAT? In my real world experiences XFS is *much* faster than EXT3 at deleting large files - as well as large directories of small files. Is your comment from personal experience? Using a 2.6.X kernel?<br>
