I'm using it for a mail spool under Postfix. I was wondering if anyone has experience with these on FreeBSD. In particular, is there any tuning I can do with FreeBSD to optimize the system even further. Is there a way (and should I even bother) to tell FreeBSD that it doesn't need to cache access to this disk since the disk is already "fast enough"? What would be good newfs parameters for such a beast? There are obviously no rotational delays, and the seek time is effectively zero to access any sector on the "disk". -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
