You may want to disable sendmail if you don't use it, or use a lighter alternative (Like
mail/ssmpt)
Add this to
/etc/rc.conf
Code:
sendmail_enable="no"
sendmail_submit_enable="no"
sendmail_outbound_enable="no"
sendmail_msp_queue_enable="no"
You may also want to disable some ttys in
/etc/ttys, every one takes up some amount of memory, the "Pseudo terminals" don't take up memory, and you can leave them there.
You may want to disable some of the periodic scripts in
/etc/periodic.conf (See
/etc/defaults/periodic.conf for defaults), some can take quite a bit of time to finish, for example this disables some daily sendmail scripts:
Code:
daily_clean_hoststat_enable="no"
daily_status_mail_rejects_enable="no"
daily_status_include_submit_mailq="no"
daily_submit_queuerun="no"
