An Intex FX440 based MB, 512MB RAM, 2 DPT 3334UW with 64MB ECC cache on
each, 4xRAID-0 for /usr/obj, 6xRAID-5 for /usr/src.

Not really.  The following really helps make to finish in record times:

/usr/src/3.0/src/bin/sh/../../usr.bin/printf/printf.c:139: macro
`warnx' used with just one arg
/usr/src/3.0/src/bin/sh/../../usr.bin/printf/printf.c:188: macro
`warnx' used with just one arg
/usr/src/3.0/src/bin/sh/../../usr.bin/printf/printf.c:229: macro
`warnx' used with only 2 args
/usr/src/3.0/src/bin/sh/../../usr.bin/printf/printf.c:362: macro
`warnx' used with only 2 args
mkdep: compile failed
*** Error code 1

NOTE:  The sub-mimute is a joke :-)  It finishes in one minute or so,
but does not conplete :-)

When the compilation actually completes correctly, it takes about
84-100 minutes.  I never just leave it alone and the machine is a
gateway, mail server, DNS, FTP, etc. so times vary.


If Microsoft Built Cars:

There would be an "Engine Pro" with bigger turbos, but it would be
slower
on most existing roads.
