Softupdates are turned on and applied to the filesystem[s] only if mount says it, i.e.: /dev/da0s1e on /usr (local, soft-updates, writes: sync 2 async 972) The kernel must be compiled with "options SOFTUPDATES" and you must apply them manually to the filesystem[s]. Compile it with optimizations turned on, because by default FreeBSD's kernels aren't optimized. Also, there are other options that you may use to enhance FreeBSD's performance. For example, consider using the "noatime" option mounting the filesytem[s]; do a "man mount". --- Stefano Riva Software Engineer - System Administrator Informazioni Editoriali I.E.
