Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG At work, I'm thinking of replacing our aging Tru64 Alpha mail server with a dual PIII running some variant of {Free|Net|Open}BSD. Most of my experience with Intel-based Unix has been with Linux, primarily RedHat. One of the things I noticed with Linux was the horrible NFS performance (that, and I don't really like RPMs--ports is much better). I'm not that experienced with NFS, and the way our mail (Sendmail, pop, and imap) server is set up requires lots of NFS traffic. (Serves mail spools via NFS, client for home directories for IMAP and stuff). Apparently, one of the large drawbacks to NFS for FreeBSD is the lack of file locking. But, it seems that lots of people use it, and even O'Reilly's NIS/NFS book mentions that locking apparently goes against the whole idea of NFS. Am I going to get in trouble for this recommendation? Or will it work OK? -- Dan Bongert dbongert@ssc.wisc.edu SSCC Unix System Administrator (608) 262-9857 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
