  It takes 6 hours with P5-100/32MB/AHA1542CF+3HDDs.  I remember it
didn't take a day with 433/16MB/AHA1542CF+3HDDs.

  `make world' makes "hierarchy mk cleandist includes lib-tools
libraries tools", then make depend all install.  Perhaps you may
restart from any target (I'm not sure).

  I recommend to separate root filesystem, /usr/bin and
/usr/obj(/var/obj) to three different diskpacks.  At least you should
separate /usr/bin and /usr/obj.  Also you can uncomment "CFLAGS=-O2 -
m486 -pipe" line in /etc/make.conf if you have enough memory.  This
improves disk load VERY well.  You can check disk load by iostat(8),
vmstat(8) or systat(1).
