Firefox 4.0 Beta 7 - Super fluid, beats everyone on sunspider

Congrats Mozilla on the release!

Odd title though for this post, for where is the "everyone"? The link shows comparisons to previous versions of Firefox, not other browsers.

One thing I hope they fix before final release though is the constant CPU usage when you have many tabs open. I thought the Panorama feature was supposed to address this. It's currently idling at around 25% CPU for me, and no, unfortunately I can't blame it on Flash. :-\

Sunspider’s not a very good benchmark; more interesting to me is that they’re nearly even with V8 in V8’s own benchmark.

Though I wonder why they can’t backport TM, or at least a subset, to 3.6; is Firefox so monolithic that improvements to the scripthost can’t be separated from the rest of the browser?

I ran the tests on my Ubuntu 10.10 laptop running Firefox-4.0 Beta8pre and Chrome 9.0.570.0 (64571) and Firefox actually beat Chrome 2943 to 3645 (or a 23% improvement) averaged over two runs.

Gotta love browser competition!

don't ever average software benchmarks, it doesn't make sense. always take the best run.

Err, your last sentence is a bit weird. First of all, 3.6 already has TraceMonkey; what's new in Fx 4 is JägerMonkey, and the integration between it and TM. Second, the Mozilla JS engine is largely developed separately (all of the actual development these days is in a separate repository, which merges semi-regularly with the main mozilla-central repo), but have you seen any other browser backporting anything other than security fixes?

Huh... I haven't heard anyone in the Mozilla world even talk about backporting to 3.6 (even to say it's a bad idea). Everyone is very focused on 4.

I'm very happy with the result. However, on some javascript intensive webpages, such as https://console.aws.amazon.com/s3/home, it hangs the whole Firefox for a little while. Hopefully with a long timeline to the release, no such issues remained.

I sometimes notice this too, but always after running a bunch of Flash vids. Haven't methodically tested it, since it's not a priority and a quick restart fixes it. But how do you know it's not Flash?

Flash runs in its own process named "plugin-container", so if Flash crashes it won't take down the rest of the browser. I'm pretty sure that if flash were eating CPU, it would be attributed to the "plugin-container" process and not the "firefox" process.
