Definitely not necessary.

Have make start up many compiles in parallel with the -j switch: for
example "make -j3". My rule of thumb for a most-effective make is 3 times
the number of processor. You will probably want a higher number just so
the strain on memory and disk is higher.

These are fairly big packages, and you're downloading them from sites
operated by mostly non-profit organizations. To save on their bandwidth and
costs, you should really make a local copy of the distribution files. An
easy way to do this is to do a "make fetch" on one machine, which you keep
up and exporting its /usr/ports/distfiles over NFS, and have all the other
machines mount that directory over NFS.

There's a whole set of special-purpose programs in ports under benchmarks,
but I assume you're already familiar with all of those which matter.

Here's an idea - try and look at the tuning(7) man page, and apply every
suggestion in reverse. I'm half-joking, but things like turning off
softupdates should really increase the number of disk accesses.
