I'm more worried about the cache. For 32 bit bytecodes, the same program
will be only half the size than for 64 bit. Or: you can fit a twice as
large program in the cache, or two of them (for multitasking). That will
mean a speed-up, and likely a vast one for programs with sizes close
enough the cache size.
