What does a "send" mean here?
Is that a instance variable access or a method activation?

On my dual 2.5Ghz G5, Io does 5.4 million instance variable accesses 
per second and 3.2 million method/block activations per second, but I 
would expect Self to be 10x faster than that, even on your dual 2Ghz 

Also, Python does 4.8 million instance variable accesses per second and 
1.5 million method/block activations per second on my machine.
