On the SPARC box that I have (128 vcpus, 32 cores, 4 cpus) the DV
encodcing/decoding proved to be the most scalable so far. I can't
say it was a speed record, but it sure was a scalability one
(on ~50 vcpus I've got about 10x speedup). The memory seems to be
the biggest bottleneck so far...

Anyway, I would be very curious to hear suggestions as well.
