Ubuntu javascript benchmark

Today i stumbled upon Sun's SunSpider JavaScript benchmark. One can measure the performance of the browser JavaScript engine here. I checked my box and found it to be pretty fine. It took 3427.0ms, ergo 3 and half seconds to run. Sounds good to me. The browser was firefox-3.5 on Ubuntu Jaunty.

dpkg -l firefox-3.5

firefox-3.5 3.5~b4~hg20090330r24021

I installed sysinfo to show you my system metrics:

apt-get install sysinfo

Feel free to post your results here as a comment.

Edit: On the same machine i ran this test in a virtual box 2.02 machine with W2K and Firefox 3.07 in 4467.0ms - not too bad. But wait - with Firefox 3.5rc4 in the same virtual machine it took only 1634.4ms. That even outperforms more then 2 times the native Firefox-3.5 on Jaunty - that is bad!

Edit: Chrome did it - Version Number 3.0.191.3. Nativly on Ubuntu Jaunty Jackelope 9.04

Can you beat this with system metrics comparable to that mentioned above?
