This scripts calls /usr/sbin/periodic, which then executes all the scripts in /etc/periodic/security. With the command 'grep find /etc/periodic/security/*', you'll find that three scripts contain a find command; - /etc/periodic/security/100.chksetuid - /etc/periodic/security/800.loginfail - /etc/periodic/security/900.tcpwrap What you could do is prepend the find(1) commands with the nice(1) command, to give the find commands lower priority. E.g. 'find -bla' then becomes '/usr/bin/nice -n 19 find -bla'.
