OK; this was with "make -j8 buildworld" on RELENG_5:

freebeast(5.3)[6] uname -a
FreeBSD freebeast.catwhisker.org 5.3-ALPHA FreeBSD 5.3-ALPHA #56: Fri Aug 20 07:26:27 PDT 2004     root at freebeast.catwhisker.org:/common/S3/obj/usr/src/sys/FREEBEAST  i386

Before patch to make/Makefile:

       1h8m1.67s real          1h33m11.20s user                24m25.74s sys

After patch to make/Makefile:

       1h8m5.90s real          1h33m4.93s user         24m13.26s sys

Before each test, I rebooted, then cleared /usr/obj/usr/src, then re-built
and -installed /usr/bin/make.

I did botch the patch the first time (by leaving a "3D" in there), but
the timing wasn't started until after the patch was done, so that should
not be especially significant.

Each test was done within script(1), within screen(1).  I cleaned up
the script files a little, and can make them available to you in whole
or in part.

Evidence of curmudgeonliness:  becoming irritated with the usage of the
word "speed" in contexts referring to quantification of network
performance, as opposed to "bandwidth" or "latency."
