On the test you linked I see Safari 2.0 getting 27 seconds compared  
to Firefox 1.5's 40 seconds on the script speed test.  That's even  
just Safari 2.0.... TOT is much faster than 2.0.  Your definition of  
"fast" doesn't seem to match up with mine. :)

Which specific JavaScript test in that chart shows Firefox to be  
faster than Safari?

Everything you find where?  You've linked to a benchmark that shows  
JavaScriptCore is faster.... not really helping your case any... :)

Who is starting from scratch?  Our interpreter has been around for

Results that you seem to have misread.... maybe you should keep digging.
