It didn't make any significant difference:
find /usr/src | cpio -pdum /target (~600k blocks):
/noraid (1 drive, softupdates):
901.70s real 6.32s user 135.73s system
944.64s real 6.40s user 135.49s system (*MAXACTIVE to 30000)
buildworld -j16:
src & obj on /noraid volume (1 drive, softupdates)
6053.86 real 7969.94 user 7601.81 sys
6040.56 real 7933.80 user 7643.17 sys (*MAXACTIVE to 30000)
(The /*raid* volumes are all on the 5 older SCSI disks, but the rest of
the system is on a newer IDE disk, which is why the IDE times are better.)
