When creating filesystems with a partition containing many small files like one containing Maildirs. Is it a good idea during installation to set frag-size in disklabel to 1024 in order to automatically increase the number of inodes as oppose to simply using newfs -i 4096? Or would it reduce performance for larger files unnecessarily. I was also expecting -g avgfilesize flag to affect the number of inodes but it doesn't and it is useable with tunefs. Would anyone mind telling me what affect it has? Thanks, Kc
