for high-volume mailservers. If "syslogd" is showing up high in "top",
and most of the syslog traffic is going to your mail logfile, you can
tell syslogd to use unsync'd writes to that file by adding a "-" to the
start of the path:
By default, syslogd fsync()'s logfiles after each write.
Another useful tip -- for logfiles/spool areas that don't need to
be resilient in case of a reboot, stick 'em in a tmpfs. tmpfs
is a VM-based filesystem, where all files and dirs reside in
the page cache and in swap, and it rocks for performance...
