In a mail gateway configuration, several people have suggested that using a tmpfs (or mfs, depending upon your flavor of Unix) would provide a performance increase (i/o). Though someone argued (on a list posting) that the buffering on normal disk operation would probably be better. Can someone shed some light on this. Thanks.
