Well, if gcc would realy work on sparc64 this would be true. But actually the
gcc in our base system now is far better in compiling 32bit sparc code - so
for non monster VM applications you will see a noticable speed increase when
running 32bit. That's upto something around 30%.

The other points are of course valid, so running 64bit has it's plus sides.
