I always referred to my 2.4M nps as >"the benchmark number". Yes, but note this doesn't mean 1 node every 400 ns, it means 2 nodes every 800 ns (ball park figures as always). I believe this distinction is important when you talk about memory trafic, because using two cpus does actually double the _cache_ bandwidth (for things in cache), and that is an important factor. -S.
