Mac Browser JavaScript Performance

I ran my browsers through these JavaScript benchmark tests. All tests ran on my 1ghz PowerBook G4. Very surprising results:

Test 1 Test 2 Test 3 Test 4 Test 5 Test 6 Test 7 Total
Camino 0.7 2.042 1.378 2.521 1.656 0.680 8.890 1.966 19.130
Firefox 0.8 18.011 4.161 2.371 1.944 0.756 12.613 2.160 42.020
IE 5.2 1.849 0.693 3.325 42.444 2.898 10.787 5.227 67.220
Safari 1.2 67.403 1.929 1.848 25.723 14.694 5.023 16.179 132.800

I use Camino as my main browser but I had no idea the JavaScript performance was that much better. Anyone else have similar/different results?
