However, you can tune the system for getting higher disk performance. First, you should enable "softupdates" on each filesystem, using tunefs(8). And, if your system has ATA disks, you could enable the write cache; the procedure is described in ata(4), but in a few words, add hw.ata.wc="1" to /boot/loader.conf and reboot. -- JMA ****** Jose M.
