Without the profiling libraries, it takes less than 8 hours to
build 4.2-STABLE on an AMD 5x86, which is actually just a fast 486.
When FreeBSD takes longer than a good night's sleep to build, I
guess I'll need to upgrade.

The speed of the buildworld process depends heavily on the speed
of your computer's memory system.  Most other tasks won't strain
the memory bus as hard.  Does your motherboard use the Intel VX
chipset?  If so, only the first 64MB of RAM are cached.  Try either
removing 64MB or disabling the `write-back' feature of the L2 cache.
The later action may allow the chipset to cache all 128MB.

You should be able to determine the type of motherboard chipset in
your computer by looking at the output produced by `dmesg.'

Hope this helps,
Aaron
