Found this little test which gives an indicator as to Javascript performance in your browser.
On my system (Windows XP on two year old Lenovo T60p laptop) i tried to run it ten times on my browsers with all plugins disabled (lower is better):
Google Chrome: 297,7
Firefox 3.5 beta 4: 340
Firefox 3.0.10: 408,9
Internet Explorer 8: 631,3
As the score is time, lower is better. This is interesing because sites uses Javascript more and more, and as we work more and more online with more applications in the cloud, the Javascript engine has a lot to say about our perception of overall performance.
I got a bit disappointed about my Atom-based netbook – specifically Ubuntu 9.04 on that machine. It never went below 1800 (Firefox 3.0.10) and on the same hardware, the Windows-browsers gives me minimums of 1500 and 2800 for Firefox 3.0.10 and IE8 respectively. Gotta find some tweaks there.
