True enough. That said, it’s hard to deny that IE 7’s JS Engine is markedly slower than most other browsers.

JavaScript benchmarks are always a funny thing. They always produce some numbers about the speed of a given platform, but it’s always uncertain what those numbers mean.

I’d recommend looking into the SunSpider, Dromaeo, and the V8 Benchmarks.

Not really, especially because IE 7 is the only problem one, and IE 7 lacks much in the way of tools/inspectors/etc.. On Firefox and Safari I can use Firebug and the Web Inspector, but everything is lightning fast on those browsers. Basically we’re just clicking and counting seconds. Certain actions take < 1 second on all browsers except IE 7, where they take 4-6 seconds, which is unacceptable for the end users.

Have you had any luck with performance tools?

Are you using any tools to test “slowness” of your rich interfaces in various browsers?
