Mine is quite lower but then being on dial-up probably accounts somewhat for the lower scores.
I’m using Opera 11.64 because I have problems with both new versions of Opera 12.

It’s even lower with IE8 but I would expect that.
Here’s Chrome’s score on my Win 8 computer:

In all honesty, I’m not sure of the value of this test in comparison to your real world browsing. Like many so called speed related this browser is faster than browser X. When in real life the differences can only be measures on benchmarked systems and by stopwatch with the differences to the human mind virtually indiscernible/unmeasurable.
So I don’t know how this bunch of tests would relate to real world use.
The only thing that I saw was the inability to run this test on IE8 at all (but I don’t use IE8 if I can absolutely help it).
It’s probably IE8. The following was run in IE 10 (Would probably also work in IE9)
Yes it possibly is, but again does it matter in the way of normal browsing, when browsing (if I ever happen to do that with IE8, unlikely) are you likely to bump into anything like this concentration of javascript.
Even in the course of browsing if your browser scored top/good marks in the tests, how would that compare to a browser scored bottom/poor marks in the tests and there is no answer to that question on the site.
For me these tests are ‘tests for tests sake’ and of no practical real world application.
If nothing else, this test did point out some inabilities of IE 8. 
Well we don’t even know why it wouldn’t work, as we have no error messages other than that script is causing IE to run slowly. Not that I care that much as my use of IE8 is rarer than rocking horse droppings.
But it still proves nothing other than it doesn’t work on that site, which a user is hardly to come across in general browsing.
I have no idea what this means but…

Hi folks,
In general we can say the higher the results the better they are, see bob3160’s results. He has beaten all. Well done, bob,

P.S. There are so many things one can do with or to a browser outside browsing: fuzzing for instance and that can be done online.
This is not every-one’s cup of tea, but some may like it.
Example: http://shazzer.co.uk/vector/Characters-allowed-as-h-in-http
Fuzzing is a kind of stress testing browsers for bugs, also helping towards better performance and improved security,

I guess the speed of the machine also affects your score, at least if i compare my score to Bob’s(we are both using Chrome).

Congrats. Not bad, not bad. That must be a nice experience for you, must look sleek and feels slick, ;D

Not sure if you were replying to me but yeah everything is loading superfast over here not just Javscript on internet pages. 
I have to admit i really don’t notice any difference in speed in real world usage between different browsers that i use over here, i feel FF is just as fast as IE or Chrome on my PC. I am sure there are small differences in loading times but we are talking miliseconds, nothing i would notice with the naked eye.
So i guess we have learned that Chrome kicks some serious ass in Javascript rendering but it really isn’t noticeable in real world usage. Besides, most of you guys are blocking JS with NoScript anyway. ;D

For what it’s worth. ;D
Hi Para-Noid,
For what it is worth, well that is obvious, isn’t it?
Some browser and I do not mention a name here is known not to be full in line with general specs, and is out to bend the rules a bit, you know, to please most and every website developer. Curving the bends, so to say. In that case the benchmark points will be accordingly lower. (Preload and Fullscreen API)
