Yeh, we've been speaking a bit on private about what he wants to do.
Generally I/O is more important that CPU cycles; and building in
parallel with hit the I/O limits sooner that the CPU (YMMV).

Dan, can you drop me on private the specs for your machine? Also, the
subset of ports you want to build and other relevant details

distant future :)
