The number I have often seen associated with the Dorado is 400,000
bytecodes/sec, which is 80 times slower than Jon's phone and 100 times
slower than John's tuned iPhone VM. I just use 0.5Mbc/sec for the Dorado
to make the math a bit simpler. Since the Dorado could execute 14
million microcode instructions per second, this would mean 28 microcode
instructions per bytecode which does seem rather high. But I really
can't imagine it needing less than 10 microcode instructions per
bytecode, which would result in a peak of 1.4Mbc/sec.
