fsck will tell you the level of fragmentation on the file system: > fsck /usr ** /dev/ad0s2g (NO WRITE) ** Last Mounted on /usr ** Phase 1 - Check Blocks and Sizes ** Phase 2 - Check Pathnames ** Phase 3 - Check Connectivity ** Phase 4 - Check Reference Counts ** Phase 5 - Check Cyl groups 352462 files, 2525857 used, 875044 free (115156 frags, 94986 blocks, 3.4% fragmentation) This is from a /usr system that's been in use for years. (note that "frags" in the last line refer to file system fragments - "subblocks", not fragmented files).
