For the starters, you're compiling two different sets of files,
one for i386 and another for amd64.  You'd better compare the
same set.  This can be done (approximately) by doing a cross-build
for say i386: "make -jN buildworld TARGET_ARCH=i386".  Also, given
the amount of memory that you have in these machines, it shouldn't
be a problem to put /usr/src and /usr/obj onto a memory disk.
